Nano Dia ~ yes, it really does contain millions of 'nano' diamonds per lead! The nano diamonds make this a strong lead, while the oils help improve smoothness. It makes an excellent pairing with the Mitsubishi Kuru Toga. This is one bold lead! Please note: The Nano Dia is being discontinued by Uni. If your preferred size is not available, we highly recommend Uni's Smudge Proof lead (which will be replacing the Nano Dia).
