Materials
Full-grain, vegetable-tanned English bridle leather gives the OB-03 a firm structure, smooth hand, and a surface that develops a richer patina through use. Natural grain, tone, and markings make every piece distinct.
Construction
Cut, assembled, and saddle stitched by hand. The traditional two-needle stitch creates a strong seam designed for years of daily carry.

Designed with purpose
A minimalist wallet for everyday carry.
The OB-03 keeps cards easy to reach while maintaining a slim, pocket-friendly profile. Its angled pocket lines give the card wallet a distinct silhouette, and the Black/Walnut pairing adds warmth without unnecessary decoration.
Built from the same full-grain bridle leather and hand-sewn construction as the rest of The First Mark, it is designed to soften, deepen in color, and become more personal with use.
