This is an original item from IRA, a company that produces leather goods and bags. The soft, grained cowhide leather is left uncut, allowing you to feel the texture of the material. The simple structure of a single piece of leather folded in half and fastened with a button gives it a smart appearance. The metal fittings can be opened and closed by turning the screw, so there is no need to worry about the keys accidentally coming off. It can hold up to five keys.
