Mitsubishi Uni Sharp Lead Refill – 0.5mm HB (100 Leads)

A refill that does rather more than simply refill—it quietly encourages better habits. The Mitsubishi Uni Sharp 0.5mm HB Lead Refill arrives in a thoughtfully designed cardboard sleeve, offering a more sustainable way to keep your mechanical pencil in steady service.

With approximately 100 leads tucked neatly inside, you’re well supplied for the long haul—whether that’s pages of notes, margin annotations, or the occasional sketch when inspiration strikes. The 0.5mm HB lead provides a dependable balance: fine enough for precision, yet smooth enough to keep your writing flowing without interruption.

Refilling, mercifully, is delightfully straightforward. Peel the seal, tip the leads in, and carry on—no spills, no fiddling, no mild despair.
