For some reason, “designer calculators” (of all devices) are a dime a dozen, but this model announced [JP] by Japanese stationery maker Kokuyo is a bit different. First, the calculator (dubbed X-VIZ) is designed to be used with one hand only, and second, it’s the brain child of famed robot designer Tatsuya Matsui.

Kokuyo plans to start selling the extra-slim X-VIZ (32×162×12mm) in Japan on May 11 for $64.

Ask specialized online shopping services like Rinkya or Flutterscape if you’d like to import one.
