Mitsubishi
Mitsubishi Pencil has been making precision writing instruments in Japan since 1887. Their Uni Hi-Uni graphite leads use a high-density polymer formulation that produces darker, smoother lines than ordinary leads — without increasing breakage. Available in HB, B, and 2B grades for 0.5mm mechanical pencils. The choice for anyone who has decided that their pencil leads should be as considered as the rest of their stationery.
