A Split Ring is a type of metal ring that has been wound in such a way that there are two distinct ends. The two full turns within the split ring allow for things to be slid onto the ring in the same manner as a key ring. When connecting two items, a split ring is very secure, as there is is no way it can easily open when you don't want it to!
Made from an alloy of metal that is nickel free. Price is per piece.
