Postalco, a favorite in the world of unique stationary has teamed with retailer, Opening Ceremony, on a series of wallets and notebooks to be sold through their stores in New York, Los Angeles, and Postalco’s Kyobashi Shope in Japan. The collection pulls inspiration from traditional Japanese geometry of the Edo Period (1603-1867). The patterns were drawn on wooden tablets called “Sangaku” and were hung under temple and shrine roofs to pay thanks to god for the discovery of the mathematical theorem.
