The case has two distinct parts (1,2) which are assembled to form a key holder. It has an opening (3) in one end into which a coin or token (4) is inserted and held in place by a curved spring (7). A hole (5) in the top of the case allows the user to push on the coin and the spring to release the coin. The spring is held between a small stop (8), near the opening, and a stud, near the back, which are on the lower part of the case.
