SIWA | Shiiwa is a brand created by ONAO, a Japanese paper manufacturer in Yamanashi Prefecture, and product designer Naoto Fukasawa. Developed from Japanese papermaking techniques with a thousand-year history, the new material "Naoron" retains the unique texture of Japanese paper while being lightweight, durable, and water-resistant.

SIWA products, where even the wrinkles and marks that appear with use transform into a unique character belonging only to the user, quietly accompany your daily life alongside your writing tools.
