200pcs Elastic Cord Locks Toggles for Drawstrings Mask Adjuster Silicone Round Cord Stops Non-Slip Cord Stopper Adjustable Buckler for Mask suppliers (White 100pcs, Black 100pcs)

I make masks (who doesn't in 2020?) to give away to various neighbors, friends, family members, strangers. But sometimes if a head is particularly small or large, I'm never sure how long to make the elastic loops. These little doo-hickeys are super easy to put on (like 4 seconds for each loop) and they make it so easy to adjust. My 2 1/2 year old grandkid has to wear a mask if she wants to start a particular pre-school and by using these she'll actually keep the mask on (for about 57 seconds anyway) far longer than she would before. Highly recommend these.OH, I almost forgot... I've used these cord locks on round elastic, as well as 1/4 inch flat elastic and then some really thin (maybe 1/8 max) stretchy string type elastic. It goes on and stays on and works easily no matter which I use.

I hoped these would be flexible enough to work on both elastic bands and some fabric ear loops, but it is only good when the loops are made from elastic. The case they come is great, the black and white 'beads' are in individual zip bags, and there are two very good threaders included. Still looking for rubber 'beads' that have slightly larger holes that I can pull fabric loops through.

Easy to apply with the hairpin-like tool (2 of them) supplied. Very soft. Feels like silicone. Have worn a COVID mask these applied to and they are gentle on your skin. Haven't washed the mask yet, so will update review when it comes thru the wash and dry cycles. Currently, would order again.02.15.21 Update: They machine wash and dry great. Did not become hard and brittle after multiple launderings and machine drying. These are my go to supplies now.

This was so easy to install and I use it on my child because his mask was a little too big. I put them on the lower part of his mask so it wouldn't put sores on his ears and it worked perfectly that way. Thank you. Someone bought us matching masks and he was a little sad that it was too big to fit his but he is super happy now. Thanks to you. Stay safe everyone.

Had to make a LOT of face masks. Wow, these toggles worked fantastic!!! They come with 2 little tools that look like a bobby pin....these tools worked great & make pulling the elastic through the toggle so quick & easy. Also loved having the black & white shipped together to give me option for the many different themed masks.will definitely order again.

These work perfect for adjusting both store bought and homemade masks. I have used them on thinner elastic pieces and some thicker ones. The thicker ones, I had to fold the elastic to get it through the hole but it works great. They are comfortable on the back of the ear. For someone that doesn't like it on the back of the ear, it is possible to put the adjuster towards the bottom of the elastic so it is below the ear.

Just what I needed! Was having trouble with my glasses fogging up when wearing a cloth mask, just couldn't get the fit right. These work like a charm! White and black, along with a little tool that pulls the cord through are included in a plastic box. Really easy to use...and now I can wear a mask with unfogged glasses, yay.

The media could not be loaded.  These little silicon adjuster beads are perfect! I've used them with 1/8" round elastic & 1/4" flat elastic & both fit well. They're easy to thread, with the tool included (see my video). For elastic sewn into masks, these work wonderfully! They have a good non-slip grip & stay where you put them.
