Review on 🎒 Pack of 60 Silicone Cord Locks for Drawstring Masks, Non-Slip Toggles for Mask Adjuster, Elastic Buckle Cord Stops for Mask Adjustment by Linda Diaz

I could only use them on a mask with a very very thin cord. All masks with regular size elastic ear loops were too big to fit through the locks. The cloth ear loops are MUCH large to fit through those locks! And the two I was able to attach to the elastic loops broke the included installation tools. Don't waste your money - tie a knot in the elastic instead, or sew a few stitches in the loops to make them smaller! I will return these!
