Suitcase is a minimal suitcase created by Japan-based designers Kazushige Miyake and Daisuke Ishigami for plusminuszero. The project is a suitcase that utilizes extremely quiet casters and a rigid aluminum frame. The uneven parts of the suitcase such as the handle and the lock have been minimized, and a single color has been used for the entire body of the product; while each and every part has been accurately constructed as part of an overall whole, the product combines both precision and a sense of rigidity and gives a sense of carefully protecting the user’s luggage. The shape of the shell and its lack of unevenness is the distinct feature of this product.
