Quality, finish, durability. Just using it to update my keychain. Used on my horse's cinch to create a clip for the breast collar.
Returned it and was charged $6 for the privilege of sending back a faulty item. Totally useless.
These are the best * i have bought, they swivel and are extremely tight and snap like the best of them! They look fantastic with my acrylic keychains. They're great, but the chains are weak so you'll have to be careful or replace frequently.
