This TPU wallet was created for the cashless era. Its minimalist design allows you to carry only the bare necessities, such as a few credit cards and some bills for emergencies. Simplicity has been pursued down to the smooth action of opening the wallet by pushing inward on both sides. The beautiful gradation of the "shallow sea," a vast ocean visible to the horizon, and the "flower robe," inspired by the pale crimson of cherry blossom season, creates a beautiful design.
