Who says diamonds are only for jewelry? They are exquisite for creating precious artwork as well. The Uni NanoDia Low-Wear Pencil Leads are infused with nano-diamond pieces to create an unusually strong and high-quality lead. Multiple lead grades are available.

I'm a fan of Pentel's Ain Stein lead. However, I was using the 2B Stein lead in my Lamy 2000 and it was breaking more then I could tolerate. So, I switched to the Uni Nano Dia and, voila, breakage dropped significantly. The Nano Dia seems as dark as the Stein, but perhaps a previous reviewer is right that this Nano Dia is a little harder.

In any case, highly recommended.

the lead is indeed durable....
Verified Purchase
the lead is indeed durable. writes well. smooth, but as you would suspect, because of their construction, the grade of the lead itself seems to be a bit harder than whats indicated on the label.
that said, its a great lead, doesnt smudge too much and the lines are dark and crisp. just something to keep in mind when making your purchase, if you are use to a softer darker 2b, you may want to try the 3b instead.

Before, my main lead...
Before, my main lead was the orange AIN lead from Pentel. I thought previously that that lead was perfect as it was dark and strong. However, I was not completely satisfied with the lead and it was not smooth enough for me. So, I tried this lead and it was PERFECT. Now, this lead goes in all my pencils and it is a joy to use because it is so smooth, dark, and especially STRONG!!!
