opus 22 is a new coin case developed to store coins that tend to overflow from mini wallets. It took 30 months to develop, and we produced 22 prototypes. The focus during product creation was on the visibility, ease of removal, and ease of holding of coins. Furthermore, we designed a lid that closes with just leather and thread, without using any metal fittings. Since 2013, Tachi, the representative, has been specializing in the retail business, planning, researching, purchasing, developing, and selling products, and in April 2019, he launched the leather brand “Age” with the brand concept of “obsessing over 1mm. ”Due to the structural nature of mini wallets having fewer coin compartments, coins tend to overflow when paying with cash. Even as cashless transactions advance, many stores still only accept cash payments, making coins still necessary. That’s why we developed opus 22. Considering that many people tend to forget their coin case and that it is seldom seen by others, we adopted pop colors. We focused on a lid structure that does not use hooks or zippers, making it easy to see and access the contents. The coin holding part acts as the lid, and special attention was given to the shape and thickness of the leather when folded. We use domestically produced Roroma leather, which, with long-term use, the surface wax blends in, allowing for beautiful aging. In addition to coins, you can store 1 to 2 folded bills, making it useful for emergencies. Tachi’s favorite usage is to use it as an evening pill case. During meals and social gatherings, keeping it in the front pocket of your pants helps you remember to take your medication. Also, it can be used to secretly carry a lot of ¥100 coins for UFO catchers. In Japan, there is a shortage of leather craftsmen, making external outsourcing difficult. Therefore, we trained inexperienced employees through a one-year training period and made them responsible for the production of opus 22.
