Review on 🔒 400Pcs Cord Locks for Face Masks - Silicone Cord Stopper Adjuster, No-Slip Earloop Toggles for 1/4, 1/8 Inch Elastic, Buckle Adjustment Accessories for Adults and Children by Doris Tran

They were perfect for making my mask's ear loops more adjustable and comfortable. Item arrived quickly and in good condition - no defects and the correct number of cord locks in black (200) and white (200). Agree with another reviewer that including instructions with illustrations on how to apply would be very helpful. I used the threaded sewing needle method and it worked well and only took me a few seconds to attach the tip to my round 1/8 inch elastic ear loops. They seem very reliable once installed. I didn't need that much but the price was so affordable, that I couldn't resist buying them. Very happy I got them,
