## Description

Uni NanoDia Color Mechanical Pencil Leads 0.5mm 7 Color Set

Review: Sono delle ottime mine cancellabili colorate.. L'unica cosa che non capisco è che quando fisso la matita rossa con il fissante cambia colore. Però è un ottimo prodotto
Review: I love this specific brand because they will never break. I have so many issues with colored lead—texture, thickness, thinness, easy to break, and smoothness and opacity—not with these. I can control everything and not worry about the lead breaking—just by going over it. The opacity and density of the color is perfect, right around HB which is what a standard pencil will start at. It’s perfect for colored sketches, if you want to blend your pencil and your color together, or whatever your imagination can think of. I cannot recommend these enough. I’ve purchased them thrice now and always been very happy with the quality. Note: it is a little bit harder to erase these, but with a high polymer pencil and a little patience, it’s feasible.

## Questions & Answers

**Q: Are tgis leads hb, b, 2b, 3b or 4b?**
A: Not positive but they feel like HB.

**Q: How many leads are in each pack?**
A: If i recall correctly, there are 20 leads per pack.

**Q: Does this lead work in artwork like graphite**
A: Kind of , many if the colors are fantastic and i use in tons of artwork however the light blue/cerulean color is a bit faint and harder to work with. But overall yes i am very pleased, with its ability, dont mistake this for a graphite pencil though, it is more of like a colored pencil consistency.

**Q: can the the lead used also in Pilot color Eno pencil?**
A: I would assume so as long as the pencil in question takes 0.5 mm lead.  It does break pretty easily, but I haven’t found 0.7 mm colored leads.
