Hole-reinforcement stickers have been around for decades, but the classic sheet format has two recurring annoyances: lining up the sticker accurately over the hole, and peeling a tiny circle of backing paper that immediately sticks to your fingers.

KOKUYO's One Patch Stamp addresses both. The tool uses a proprietary advance mechanism that feeds and applies one sticker per press, like a stamp. There is no release liner at all, so nothing to peel or throw away. A registration guide molded into the cap lets you position the tool over the punch hole before pressing, turning a fiddly task into a repeatable one-step action.

The stickers themselves are made from transparent PET film (0.05mm), so any text or printed lines underneath remain visible after reinforcement. When the roll runs out, only the inner cartridge needs replacing, not the whole unit.
