InstaMorph Reusable Moldable Plastic | Thermoplastic Beads, Meltable Polymorph Pellets | Lightweight Modeling Compound for DIY Crafts, Sculpting, Cosplay Accessories | Temporarily Repair | White, 3oz

I purchased this on a whim as I was restocking some hardware and glue and it came up with great reviews. When it first arrived I thought I would just try it out to see how it worked -- since it is supposed to re-useable it wouldn't be a waste and if it didn't really work as well as everyone said then I could return it. It was VERY easy to use. I put 1 cup of water in the microwave for 1 minute and my digital thermometer read almost exactly 140 degrees (I have tried it since at even higher temps and it still works great -- just test the water temp before plunging your hand in!). Once hot I dumped in 2 tablespoons of the little beads waited 2 minutes then picked up the rubbery lump right out of the water and started forming it. It was very moldable (and fun) and set up hard and strong in about 3 minutes. But that was just testing it out... The "Very Handy and Surprisingly Effective" part came later when my wife asked me to fix her toilet? The plastic nut that holds the handle had cracked and while the company graciously said they would ship a new one for free, they also said it will take several weeks. Several weeks without a flushable toilet in the Master Bedroom isn't an option so, I heated up a cup of water and dropped in about a table spoon of InstaMorph. Even 1 tablespoon was more than I needed, but one of the great parts about this stuff is you just put the unused stuff back - no waste. After 2 minutes in the warm water I took it out and formed it into something like a gummy worm, about as thick as a straw and 2 inches long then simply wrapped it around the threads and squished and formed it a bit to make sure it got in deep. A couple of minutes later it was HARD PLASTIC and holding on very tight. I used pliers to un-screw it and looked in amazement at this perfectly formed replacement nut (I could easily have used a crescent wrench to make flat parts for tightening too). Looking at it installed I realized I probably won't even need to put the replacement nut on when it comes. I will try to use that moment as a reminder to come back and update this, but know that if I haven't updated this yet, then it is probably still working. Clean up... none. No mess or fuss, just dump the water (it is all non-toxic) and put any leftover bits away to reheat and reuse later. I did decide to form them into several long strands instead of one big lump, though, just because they will heat up faster and it seems like a useful shape to start with. Net conclusion is that I'm really impressed with this stuff and recommend that everyone have a little bit around for quick fixes.

InstaMorph is an interesting, if slightly finicky accomplice for all sorts of unexpected uses. The container yields BB-sized balls of mostly opaque white plastic, similar to the appearance of the robot skin in I, Robot. When dropped in a bowl of hot water, they'll turn transparent within fifteen seconds and stick together (and to the bowl). You can then drain the water and prod the resulting soft and sticky mass onto any wet surface to mold. The plastic doesn't retain enough heat to burn. Molding properties are similar to modeling clay. It's very easy to join and smooth edges with your hands or flatten a piece as if it were cookie dough. You can manipulate the shape for about three minutes until it begins to harden. It'll take another ten minutes to reach final hardness, or you can speed the process by putting it in the freezer for a few minutes or running it under cold water. Beware: InstaMorph gets extremely tacky once it begins to set. If you're molding it on surface that it's not supposed to stick to (e.g., the batteries under the battery door cover I just made) and you make a mistake, don't attempt to pull it off while it's still partially pliable. You'll just leave a plastic residue that'll be almost impossible to remove later. If you wait until it hardens, it'll come off in one piece and you can start again. When totally hard, strength is similar to standard, non-specialized toy plastic. It is not at all brittle and will bend under load. While you can cut very thin (under 1/16") sections with scissors, it's almost impossible to tear at any thickness. I created a simple tube about 1" in diameter and 1/8" thick and was able to stand on it with minimal deflection. You can't weaken the material with handling. Even concerted rubbing doesn't put enough heat into it, though a fingernail can scratch it. If desired, the final product can be painted or epoxied to other surfaces. It's best not to store remnant pieces in thick shapes because they'll take much longer to heat through. Just make a thin pancake and cut it later with a pair of scissors. The only negative of this product is that it has a noticeable, albeit subtle, scent. Handling will convey this scent to your fingers. I wouldn't go so far as to call it a residue, but any smell at all implies at least some material transfer. Given that the FDA approves medical grades for use in the human body, I'm not terribly concerned about health consequences, though I probably wouldn't attempt to microwave this product.

Performed just as described. Melt point is exact. Easy to shape when melted. Easy to cool and harden and remelts when placed in the right temp water. I keep a small pan of hot water on standby with a thermometer to ensure temp regulation until I'm done working, or reworking, my projects. This also allows you to add or subtract as required. Take note: adding new melted material to existing hardened forms never works well unless both parts are in full "melt" form.

Needed to use a joystick left handed but the hand rest is on the right. Looked through lots of model plastic options and reviews and chose InstaMorph. Created a small frame out of wood on the joystick, melted a small amount (not knowing how much I needed) and pressed it into place. Very easy, very pliable, quite solid though like 'heavy jelly'. Needed more, so melted more and just added to the existing. Left to harden and was delighted (and pleasantly surprised) with the outcome as InstaMorph had also stuck to the joystick itself - I had planned to screw it on once hardened but not required. After trying out, the shape was raised a little too much at the back. I tried sanding it down and to smarten up the sides but the small electric sander generated heat I guess as the plastic just became congealed. So used a hairdryer to heat up the area I wanted to smooth out and once hot I could flatten it with my finger. Then painted it just because I could. It's not pretty but it's 100% functional and exactly what I needed. First time posting pictures but with the different feedback in the various reviews it is difficult to make an informed decision. I was so impressed (and surprised by the result) I thought the product deserved a pictorial review.

This product is great for small crafts or rolling out large sheets to create a smooth surface over props. Whenever things are touted as "easy to use" and safe for children, I doubt that the product is really THAT easy to use, but I'm happy to say, this is definitely as advertised. InstaMorph was fun and easy to work with. I heated the pellets in a pot of boiling water and pulled it out with tongs. The plastic was warm but not hot enough to burn. When heated, it has the consistency of Silly Putty and it will easily stick to itself. That said, you should have an idea of what you want to do as I clocked about 1.5 to 2 minutes of sculpting time before it gets too rigid and needs to be back in the water. It was very easy to smooth surfaces out by just dipping it back in the water and rolling the piece on a smooth surface or smoothing it out again with your hands. The hot water acts somewhat like slip with clay. One of the main things I liked was that you can keep reheating it so that mistakes and scraps are reusable! For my project, I rolled it into a sheet about 1/8" thick and it was easy to draw my design on and cut with regular scissors. This is a great material for making lightweight pieces whereas using Sculpey and similar products can get heavy even if you use a foil core. I also found that it accepts paint (both spray paints and craft paints) well without priming the surface. You can also glue directly onto the surface with something as basic as Elmer's School Glue. I am very pleased with my purchase and plan on using this for many projects to come. Definitely recommended!

I used it to make a replacement zipper sleeve for my backpack. It really is a very tough material. However, it's not as malleable as I expected during the molding phase. So, you won't be able to do any intricate work like making gears or such like I wanted to do. Also, it doesn't stay mold-able for very long. You have maybe 1 minute out of water before it firms up enough to prevent any further work. I tried to fix my a hole in my acrylic retainers with this after seeing how many people have used this to make teeth but that was a failure. It has no adhesive properties so the patch keeps falling off. Another thing I tried was to color this with a permanent market but that didn't work either because it's not porous. Tip: if you accidently heated up too much of this stuff, take the remainder and flatten it into a very thin sheet. If you ball up the extra, the heat of the water will have great difficulty penetrating to the center and you will be forced to throw that out.

Problem: 1) Job interview tomorrow 2) Very obvious missing tooth 3) No job=no dental insurance (and deductibles were insane even when I did have insurance). I was very nervous about this, and quite upset that I could not find this anywhere in town (I hate mail ordering anything). Temptooth is quite a bit more expensive and it would take 3-5 days to get it. I ordered this yesterday, paid $5 for one day shipping, I got it today before noon. Right off the bat, within minutes, I was able to make a pretty decent tooth. Within a half hour I made a couple. At the moment, they're sitting in coffee, hoping they get a bit of a stain to match the rest of my teeth, so I will include photos as soon as I'm done staining them. I saw some negative reviews, I'm not sure what the problem was for them, but this stuff works just fine for me. Sure Temptooth might be easier to mold, but this isn't bad at all, you just need to be a little creative. The teeth fit very well, won't fall out and even before staining, they aren't that noticeable from a few feet. I'm quite confident they'll work out just fine for the interview, and I can always make better ones later. This product is amazing to have around the house. I gave some to my daughter and she had a great time playing with it and making a little teddy bear that hugs a pencil. It's actually quite fun to work with . I could think of thousands of things I could fix around the house with this stuff. In fact if I was in an emergency situation, this stuff would be extremely valuable, as you could shape many useful things out of it within minutes just using some hot water. Not sure what the negative reviews are about.

I used these to make fangs over my natural teeth for cosplay, and they worked very well! Following a tutorial for whatever you're trying to make is what I would recommend :)

I bought this item thinking that I will be able to easily mold things or remold (as advertised ) but it appeared to be uneasy in molding and after the first boiling process, the substance becomes very sold even with reboiling!! Don’t recommend it.

My daughter uses it for coz play, but it has many other uses. Best poly morph, it does not crack after reheating multiple times.

I made a fake front replacement tooth. Works like a charm! Saved$1500 at dentistry

Got this to make a small part for my camera but I'm sure I will find other uses for it. Highly recommended !

I bought this to make lil fangs (I got influenced by tiktok AHAHA). It is very easy to use but tbh I only used it for the fangs and got bored after a while since I don't do cosplay LIKE THAT. I will prob use it again one day but tbh it just sitting there collecting dust LMAOOOO. ITS GOOD THOUGH. GO GET UR FAKE VAMPIRE TEETH YALL
