KAMAKURA SIGNET — The Masterpiece Collection
Rare, time-honoured natural materials, hand-finished to last for generations. Every seal is finished by hand in our Kamakura atelier — practising the craft since 1898, across four generations of the Tsukino family — by masters holding Japan’s First-Class National Certification, in the Tsukino Kissotai script found in no other workshop.
hand-finished to endure, and to be handed down — a personal mark made to outlast the page it is pressed upon.
