The listing, Mini Horse Bit Keychain has ended.
This is a key chain made to look like a bit for a horse bridle. It is missing the second key ring but you could put one on there, or find 2 of the same size to put on. It is around 3 inches long without the ring. I am not certain but I think it may be made of actual brass. There seems to be a nice green patina happening there at the intersection that I tried to capture in the pics. The keychain is movable as you can see and it can hold 2 different sets of keys with another ring attached.
