Uni Nano Dia Colour Lead Refill Mix 0.5 mm

Uni Nano Dia Colour Lead Refill Mix 0.5 mm introduces colour into everyday mechanical pencil use, designed for writing, annotation, and light sketching.

At its core is Uni’s Nano Dia technology, incorporating millions of nano-diamond particles into the coloured lead formula to improve strength and smoothness. Compared to traditional coloured leads, the writing feels more stable and resistant to breakage while maintaining clean erasability with a standard eraser.
