120 PCS Black Adjustable Soft Elastic string cords Buckle adjuster with 2 pcs crochet hook ,Suitable for all different sizes of mask straps bands

As expected...

These are decent quality for the price and seem they will get the job done. I have purchased before from different sellers (no longer available) but I ran out of black and still had white to compare. At first glance I noticed the holes were a little bit bigger but still fits 1/8" elastic. Also the cutout of these is a little messy. What I dont really like is that they're not nicely-evenly smooth in shape, and with fair scratches, it almost looks a little used. I needed them right away so will still use but I'll keep checking back with my previous sellers. The tools it came with is convenient but I'll likely still use the 'bobby pin' -like tool I received with my other orders because its easier.

Okay, so, a few weeks ago, I bought some oversized masks from Target impulsively since I overestimated the size of my fat face at the time. The mask would simply not stay on my face due to the length of the ear loops. Waste of money, right?Yeah, I might be throwing away more cash buying these adjusters, but at least I don't have to feel bad seeing those gigantic masks hanging in my closet, never to be used by anybody anymore. Thanks to these babies, I got these masks custom fitted about three minutes after they arrived at my door. Bam, done, money well spent!Get these for your customs, oversized buys, or simply annoying fits (my blue mask in the picture was fine but it's default adjuster kept bending my ear the wrong way while I barely notice the size and feel of these ones).

These are literally the best thing ever! I had low expectations and surprise, they work perfectly! They hold really well, yet slide when you need them to. They are easy to feed the ear strap through the rubber bud with the tool they provide and they saved me on all my Korean KFN5 Masks where the ears straps aren't tight enough that we need for a good seal. So grateful there are people out there, inventing things like this fast! Highly, highly recommend!!

My daughter is constantly pulling the stoppers off of her mask, and these have really come to the rescue. I do have a few masks with thicker straps that are harder to get these onto, but for the most part they are easy to get on, hold securely and are comfortable.

These are great, I use them to help my 3-year old's mask fit her better. Great value for money, no problems at all except that 1 out of the 4 crochet hooks (I've ordered twice, each order comes with 2) was malformed and didn't work. Hasn't mattered for me since I had 3 others.

Loved the adjusters. I like that it is made of silicone, so they are better at locking on the face mask string than the plastic ones. Only thing is that I wish there had been a small note as to how to put them on. It was easy to figure out. Just remember to go thru the small hole then pull the mask chord thru it as this works as the "lock mechanism". Have used them on several masks now and they work perfectly.

I have a couple of face masks that I couldn't wear because there was too much elastic on them and the masks would move around. I bought these adjusters and after a few moments trying to figure out how to attach them using the crochet hooks, I got them on! I really needed a few, so I don't know what I'm going to do with the 112 I have left, but if anyone I know has the same problem, I will definitely recommend these! Instructions included with the package would be a help for the clueless, by the way.
