Dense, dignified, and refined in the hand — black buffalo horn is the classic material for a personal seal of standing.
Why this material
- Premium black water buffalo horn, carefully selected for tone and density.
- Smooth, polished finish that deepens in lustre with age.
- Hard and durable — built to hold a crisp impression for decades.
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 professionals and business owners — a seal for contracts, agreements, and the documents that mark a career.
