Mitsubishi Uni Sharp Lead Refill – 0.3mm HB

A small object with a surprisingly noble purpose: to ensure your mechanical pencil lives a long and useful life, rather than an untimely trip to the bin. The Mitsubishi Uni Sharp Lead Refill offers a neatly considered alternative to disposable habits, arriving in a recyclable cardboard sleeve and designed for effortless replenishment.

Each pack contains approximately 64 leads—enough for around two full refills—so you’re rarely caught short mid-sentence or mid-sketch. The 0.3mm HB lead strikes a pleasing balance between precision and smoothness, making it ideal for fine writing, detailed notes, or those moments when neatness feels non-negotiable.

Refilling is mercifully simple: peel, tip, and carry on. No fiddling, no frustration—just a quiet return to writing.
