Mitsubishi 0.3mm Smudge Proof Leads

This is a plastic tube refill of NanoDia leads for 0.3 mm mechanical pencils, with nano-diamond particles fused into the graphite so that the tip resists wear and breakage.

The 0.3 mm lead is recommended for fine-detail writing, small handwriting, planner annotation and technical sketching. Each lead measures 60 mm in length (2.36") at a diameter of 0.3 mm (0.012"). Available in the full range from 2B to 2H.

Mitsubishi Pencil is a Japanese company founded in 1887. One of the country's oldest pencil makers, they have produced writing instruments prized for the precision of their graphite and the longevity of their industrial design. The "Uni" brand was first introduced as a line of rollerball pens, and has gradually expanded to all of the company's innovative products.

Made in Japan.
