Uni Nano Dia pencil lead is a new technologically advanced pencil lead that is super tough with a smooth crisp finish. Nano Dia lead takes its name from the 400 million nano diamonds which the pencil lead is constructed from that gives it the strength.
This is combined with a new high viscosity silicon oil compound for enhanced smoothness and a deeper black colour. Nano Dia pencil lead is supplied in tubes of twelve 0.7mm leads and a choice of 2B, B & HB grades.
Available individually (12 leads) or further savings can be made buying in packs of 12 tubes.
