In Japanese, Sen refers to a line — precise, intentional, and uninterrupted.
This wallet follows the same principle.
SEN is built as a front-fold form to reduce bulk and friction in daily carry. Cards sit forward for faster access. Cash folds cleanly without creating thickness. Every panel is measured to remove excess rather than add features.
Pure full-grain leather defines the structure. It is left uncorrected, allowing the material to age naturally. Marks appear. Edges soften. The wallet adapts to use instead of resisting it.
SEN does not try to organize everything.
It focuses on what moves with you every day.
This is a wallet for people who value clarity — and understand that refinement comes from restraint.
