I need to purchase about 50-100 of these clasps that are the same diameter as a standard keyring, but rather than spreading the overlapping metal circle apart to fit a key in, you spread it apart and it opens right up. It has a tiny hinge on one end and the circle meets on the opposite side. When you pull it apart, it resembles an uppercase, elongated C.
Do you know what this is called, and more importantly, do you know where to purchase them?
