Review on 30pcs White Silicone Cord Locks, Adjustable Buckles for Drawstrings & Toggles by Tara Ford

They work great and are easy to fit if you watch the instruction video before you start. Unless. You will surely have a disappointment like me until I went to the product page and watched the video. The inclusion of two needle threaders in the kit is very valuable, since with frequent use one of them can get lost. I used to tie the cord to the mask, but this required more cord so I could only trim one side. With these little locks I can trim both sides making it easier to position the mask correctly. I hope that the locks will not slip when the mask is put on and taken off many times.
