Why it matters
Most payments now happen on a phone, yet cash-only parking lots, small shops and the occasional connectivity failure keep many people carrying a full-size wallet just in case. ONE+ is designed around that contradiction: keep the minimum cash you need, without the bulk.
Rolled, not folded
Instead of folding, ONE+ wraps cash inside a long strip of leather and closes with a snap. The routine the maker describes is simple: unsnap, unroll, pay, roll it back up. According to the maker, the wallet measures about 22mm thick when closed, with room for up to 9 bills plus a dedicated coin space, so change from a cash purchase has somewhere to go.
Tracking and carry options
There is a space to hold an AirTag, folding the tracker into the wallet itself. ONE+ also supports multiple attachment styles: a carabiner for hanging it from a bag or belt loop, and WAVE CLIPS, a key ring the maker says uses a wave-shaped series of arcs so keys slide on through the curves rather than being forced into a split ring.

Leather with character
The six colors carry over from earlier models in the series. The maker emphasizes the leather's natural variation rather than a uniform finish, so each piece is meant to show its own grain and texture and to develop with use. ONE+ builds on a series that, according to the maker, was conceived to carry minimal cash in the cashless era without sacrificing usability.
