Uni NanoDia Erasable Mixed Color Lead 0.5mm

Uni NanoDia Erasable Mixed Color Lead 0.5mm combines durability with clean erasability. The lead is 40% stronger at the tip than previous versions, resisting breakage during use. Infused with 400 million nanodiamonds, it delivers dense, smooth color with minimal scratching. Unlike standard colored leads, this formulation erases cleanly with a standard eraser—ideal for sketching, studies, and corrections. Each pack contains 20 leads (60mm length) in a recycled resin case.
