Black Plastic Cord Locks - Spring Loaded Elastic Drawstring Rope Fasteners for Shoelace Replacement, Sports, Backpacks Review

These work if you use them to tie bags. Do not use these handles to attach goggles or masks as they are bulky and heavy.

I've been looking for clasps like this for elastics that I use on surgical bouffants that I make for work. They are the perfect size and are spring loaded. The price was great and the delivery speed was super fast. Thank you!

Order arrived quickly. They are stronger than I expected and very well built. After using them on cloth mask ties, I've run them in the washer and dryer dozens of times. Of the 30+ used, none broke or failed.

Mediocre spring tension. Mediocre casting accuracy and deburring. round hole in body; Square hole in the piston. Due to some difficulties, a larger elastic rope or paracord can be threaded through the item. Seems to work but I won't buy it again.

This is exactly what I was hoping for, just make sure to test each one out a few times before adding it to your projects as some of these stay open . , some won't open despite the force, and some have a misplaced spring. In general, this is a small percentage of the entire bag, so I've decided not to highlight the loss of those few.
