Business card case made by the Japanese manufacturer Claustrum made of high-strength and stainless steel sheet can be opened and closed with one hand by pulling or pushing the thumb. The black surface changes with the first touch. The resulting lively patina quickly turns the case into a unique individual. A felt insert protects the contents.
