12pcs Cord Lock, Double Hole Round Ball Plastic Spring Cord Locks, End Stopper Fastener Slider Toggles Clip for Drawstrings Lanyard Paracord (12)

They work , good holding power look to be durable

I use these with rubber cord to clamp delicate objects after gluing. They work great to hold tension on the objects until the glue dries.

Great way to prevent drawstrings from coming out of your clothes. It is very easy to use and secures very well on the cords. It looks good, like it belongs with whatever you used it for. This was used for a windbreaker so the cord won't come out of the jacket and will never go back in, and keeps it in place.

Super impressed by an inexpensive pop cord lock. This may sound stupid, but I worked in the outdoor industry and these little guys come in handy. Especially when a knot would be annoying to undo all the time. I simply got them for some pants. Dudes are strong and hit larger diameter cords thru them. If I need more I’ll definitely be buying these again.

I used these for drawstring on some chef pants. Problem is they do not hold the string under much load. I have to re tighten them often which isn’t ideal if you are trying to hold your pants up lol!

Tightens and holds well

Love them. Works great for my great grandson with keeping shoes tied and pants with draw strings up!!

Good
