OCEANTREE Cord Locks for Mask, Elastic Adjuster Silicone Cord Stopper No Slip Earloop Toggles for Drawstring Buckle Clasp

Could not get them on most of the kids mask do to they use larger loops. In fact, most of the adult masks that also use the thicker loops. Works fine on the string type.

I recently bought some new masks for my mom and myself and a few didn’t fit right. They were just too loose for me to feel safe. Some were actually slipping off my mom’s face exposing her nose. (Her face is narrower than mine, so it was more of a problem on her.) I had one mask I bought that came with adjusters similar to these so I knew you had to be able to get them.I found these on Amazon and they arrived within a few days. I used a bobby pin to slip them onto mine and my moms masks. It wasn’t much harder than the thread method probably is.Point is the masks fit great now. No slippage and if these little things break or something I have plenty to spare. I consider it a good buy thus far.

This review is for the OceanTree cord locks for face masks.So glad we bought these! We kept losing the ones that would come with our masks to our washing machine (they must be delicious).These are plain white. They are a bit hard to thread onto the mask elastics but that is good as it keeps them from falling off. I've yet to lose ONE cord lock in the washer since we bought this brand.If you're washing them with something that can bleed color (think dark rinse fabrics like denim), they WILL get that "color-cling" but really, that's a non-issue for us. They're working as intended and I have soooo many left that we'll be set forever. =)I recommend these, it's a good product!

I use these little cord stoppers to make adjustable masks for my etsy store. They have improved the quality of my masks so much because they are an easy, quick way to make the masks adjustable. They slide up and down 1/8 inch elastic easily, but are tight enough to stay in the position places.My only beef is that out of the many, many packages I have bought, one of them was full of cord stoppers with too big of a hole. They are supposed to have a tiny hole on one side and a bigger hole on the other, but these had a big hole on both sides. They were still functional, but mean that the hold is not as tight and they could slide out of position more easily. Again, this was one batch out of many, and I probably could have gotten a return/replacement if I tried. I didn't try and continue to order these and have not had a problem since.One note: I thought I didn't need the directions on how to thread the elastic through the cord stopper, but I was wrong. I wasted a good 15 minutes and a lot of frustration before reading the instructions and seeing how easy it is.

These are a great little aid for making my masks more snug. My kids and I have narrow faces and so many masks out there don't fit snug. We have typically knotted ear loops that were too long, but that gets to be annoying.These are a great way to make the ear loops adjustable. They are easy to get on the loops - I used a bobby pin. They have worked with cloth masks and with the disposable surgical masks. Now our masks fit much better, which is not only more comfortable, but also minimizes gaps that would be more susceptible to Covid cooties.

These cord locks are not the easiest to put on because of the size of the whole. But it has nothing to do with the product but just what it is in general. Great value, good amount

I have made about a hundred masks and thought I was done, but in a resurgence of ambition I made a new batch and ran out of cord stoppers so I placed a quick order for the first ones that popped up. I have ordered some that look like these barrel style before, but these seem a little less secure than the others I have used. The small hole is a little bigger than what I used in the past and they tend to slip a little on my preferred elastic which is thin and round, comparable to what is used on the blue pleated disposable masks that lots of people have.. These work fine on heavier (1/8-1/4inch) elastic. There's nothing really wrong with these, especially is you are using flat elastic. Just a little more slide than I prefer.

I needed to replace adjustable locks for my masks. Didn't realize you could replace them, but Amazon was there with options. They're easy to replace. Happy I didn't have to buy the entire masks. They arrived quickly and properly packaged. I recommend.
