ResOlution Caps Universal Caps for Cleaning, Storage, and Odor Proofing Glass Water Pipes/Rigs and More - Black

This worked great for me. The silicone pieces fit (whompit) and were watertight. Cleaning is now a breeze, no more nasty glass

These make cleaning much easier. The different sizes are nice. The cleaning time these save me is priceless. I should’ve gotten these much sooner

This kit works great. It fits my super thick tag glass bong perfect and the small stem cap it has makes cleaning down stems and bowl heads so much easier.

Excellent, high quality product! These make cleaning a breeze and I would highly reccomend them. They don't look like they are airtight but they are. Instead of using alchohol and salt to clean my glass piece, I now fill the entire glass piece with a cleaner called Grunge (Amazon sells it) and put these end caps on and let it sit overnight. The next morning I pour the Grunge back into the bottle (it is reuseable for a while and is kind of like a thick goop) and rinse the glass out well and it is sparkling clean! The combination of the RedOlution caps and grunge cleaner means no scrubbing at all or vigorous shaking to get the resin off. I have used these caps for the salt and alchohol mixture as well and having these on means that you can really shake the hell outta your glass without fear of accidentally spraying yourself or loved ones in the face! I have already reccomended ResOlution caps to many friends. ALSO A TIP...If you haven't heard of a Dopestrap and own a large glass piece/waterpipe, please get one! It is a super durable, colorful, stretchy handle you put around your glass piece that allows you to pass it around easier, move it quicker, clean it better, ect. It is really really fantastic and is like $13 and even having that alone helps SO much when cleaning. If you google it the first result should be the website. :) Have a great day!

First time using it to clean my bong and the large cap flew off across the room while i was shaking it. I'm assuming its because it was my first time using it and maybe I didn't have it on properly (even though the smaller one stayed put). Anyways, the large cap just vanished. I moved everything out of the room one by one and moved every piece of furniture as well. It's gone. Currently substituting it with a piece of plastic wrap and some rubber bands. Smaller caps work well though 10/10

Perfect for keeping things neat and clean. Not to mention smell-proof if used correctly.

These silicone caps really are durable long enough to last through all your collections of glass to clean and so on and so fourth. Cheap little product goes a long way when your favorite peace’s are shelf clean.

Love these for cleaning. I haven't tried silicone plugs, as I was sold on these since they were quoted as "travel friendly". I've noticed as well that after several uses they DON'T stink! Which is a major plus if it stays that way, since silicone has a tendency to absorb odor. If you have someone who uses water pipes frequently, these are a lovely improvement to the cleaning process.

Works exactly as described for cleaning! I use this to prevent smell as well, it’s not completely smell proof but still works better then nothing!

Worked great but make sure your bong and caps are dry other wise they can slip off. Happened to me once but once I figured out it slipped off because it was wet, It didn’t happen again. Great product. Would buy again. 10/10

This is a great set of cleaning caps for all opening sizes

I use this for a glass water pipe and it works wonders! Definitely recommend

Great like usual, shipping took a little under a month though.
