Smudge-Proof Mechanical Pencil Lead Refill - 0.5mm – 2B

High-density nano-formulated Japanese lead engineered to resist hand friction and highlighter smearing.

The Uni Smudge-Proof Lead (ULS0540 Series) solves the most common headache of daily pencil writing: smeared margins, smudged hands, and dirtied paper. Utilizing Mitsubishi Pencil’s proprietary particle-binding formulation, the lead adheres tightly to paper fibers upon contact rather than leaving loose graphite dust on the surface. Even under direct hand friction or when dragged over with water-based highlighters, your lines remain crisp, sharp, and smudge-free. Housed in a minimalist sliding case, the dispenser opens smoothly with a one-handed thumb slide to release single leads without accidental spills. The 60.0 mm (2.36 in) graphite cores offer an exceptionally smooth glide, dark contrast, and superior snap resistance, making them ideal for everyday note-taking, drafting, bullet journaling, and left-handed writers.
