Review on 🔒 100PCS-Black Cord Locks for Masks: OCEANTREE Elastic Adjuster Silicone Cord Stopper No Slip Earloop Toggles for Drawstring Buckle Clasp Spring by Kelly Caballes

I use these little cord locks to make adjustable masks for my Etsy shop. They have greatly improved the quality of my masks because it's an easy and quick way to make masks customizable. They easily slide 1/8" up and down and are stretchy but snug enough to stay in place. My only complaint is that out of the many, many packs I've bought, one was full of cord locks with oversized ones They were supposed to have a tiny hole on one side and a larger hole on the other, but they had large holes on both sides.They still worked, but that meant the grip wasn't as tight and they slipped more easily Again this was a batch out of many and I could probably get a refund/replacement if I tried.I haven't tried ordering them again and haven't had any issues since.One note: I thought I would don't need instructions on how to thread the elastic through the cord lock but I was wrong I wasted a good 15 minutes and a lot of frustration before reading the instructions and seeing how easy e it was.
