Review on 🔑 Pawfly 14-Piece Flat Key Rings System: Ultimate Keychain Ring Set for Home and Car Keys Organization Attachment by Chris Santos

I bought these to attach tags to dog collars. He's a 58-pound stuffy with a thick neck. They had his tags attached (they all have fragile metal rings that you have to bend beyond repair to get at the thick collar ring). Thanks to running, ball games, tug-of-war, rolling on the lawn, and plenty of insults from his hind paws scratching his neck (he has a skin irritation that heals), they got through it with no problem. It does not deform, does not break, does not crack. Once I even attached a leash to a keychain instead of a collar ring and didn't even notice until I was about to remove the leash. I am impressed. Good buy.
