Premium Amber — warm, luminous, naturally translucent.
Fossilised tree resin, millions of years in the making — warm in tone, light in hand, and quietly extraordinary against the page.
Why this material
- Genuine amber with natural translucency and warm honeyed tones.
- Light, comfortable, and refined in everyday use.
- Each piece carries unique inclusions — no two seals alike.
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
A graceful seal for those marking a new chapter — weddings, openings, anniversaries — and a memorable gift between generations.
Premium Amber Hanko
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.
