Japanese Blue Titanium — aerospace-grade, anodised deep blue, virtually indestructible.
For those who want a personal seal engineered to outlast a lifetime. Modern in character, uncompromising in build, refined enough for the documents that define a career.
Why this material
- Aerospace- and medical-grade titanium — resists rust, wear, and time.
- Anodised in a deep Japanese blue, with a clean, contemporary presence unlike any traditional material.
- Feather-light in hand, yet built for the most consequential signatures of your life.
A Case as Crafted as the Seal Within.
Made exclusively for us from genuine kimono fabric, each case is patterned with a traditional Japanese motif — animals, flowers, flowing water — a small work of art that honours the seal it holds.
Who it’s for
Suited to executives, founders, and collectors — a seal for contracts, agreements, board resolutions, and the milestones you intend to stand by for decades.

KAMAKURA SIGNET — The Precious Stone Collection
precision-engraved in our Kamakura atelier — a workshop that has practised the art of the seal since 1898, through four generations of the Tsukino family. Each seal is precision-engraved by masters holding Japan’s First-Class National Certification in seal engraving — a distinction shared by fewer than one hundred artisans in the country — in the Tsukino Kissotai script that exists in no other workshop. Among the rarest materials we offer in a personal seal.
A one-of-a-kind work, carved once for a single name. Not a stamp to be used and discarded — an object to be owned, and passed on.
