Designed for people seeking creative balance away from the daily grind, each Blackwing Colors pencil features a unique soft and smooth color core designed specifically for coloring. Each pencil features the same semi-hexagonal barrel found in the graphite pencils and a metal end cap that adds a bit of weight, giving the pencils a comfortable, balanced feel.
These are great. I'm not a pro, but use them to highlight construction drawings at work and they're very nice. Even shading, great color selection, high quality wood, etc.
