Uni NanoDia 0.5mm B Pencil Lead 2-Pack

Uni NanoDia 0.5mm B Mechanical Pencil Leads deliver an unparalleled blend of break resistance, silky-smooth glide, and rich graphite darkness. Formulated in Japan by Mitsubishi Pencil, each lead core is infused with approximately 400 million nano-diamond particles per piece. This advanced nano-composite structure dramatically strengthens the lead against pressure while reducing friction on paper. Packaged in two compact dispenser tubes with 40 leads each (80 leads total), this set is essential for everyday note-taking, sketching, and standardized exams.
