Review on Key Ring/Key Chain by David Boone

I bought a similar size at the hardware store but there were only a few. After they disappeared I wanted to find a place to buy more. They work great with zippers. I've even used one to fix a broken zipper and put this key ring in the part that originally helped the zipper close itself. I think 50 would make a big difference but I'm glad to know where I can get more if I need more.
