OCEANTREE Cord Locks: Elastic Adjuster Silicone Stoppers for Secure Mask Earloops

K L: 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!

bluesky: 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.

JR: I received some KF94 face masks, while very comfortable they seemed to be not quite tight enough. These cord locks seem to do the job in shortening the ear loops of the mask thus tightening up the mask to the face for a better "seal" …. If your mask ear loops are to big, I would recommend them.

Awesome Aunt JessAwesome Aunt Jess: 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.

K. SweereK. Sweere: Other reviewers have said it, and it's true. Quality control is not perfect. had one (unusable) poorly formed cord lock in the bunch, but the rest were usable.

Overall, they work well. Because the elastic I had purchased in July is starting to shrink (after many washes) I decided to replace the old elastics with longer elastics. Not only does this allow me to add extra length to take into account the gradual shrinkage of the elastics, but it also allows each individual in the household to adjust the elastics to fit as needed. Wish I would have thought of using these sooner.

I use a loop turner (a tool typically used for pulling elastics through casings) to pull the elastic through the locks and that works well; doesn't take long to get the locks on the elastics.

I will likely buy these again when I run out.
