Query: Wonderful!

The lead DOES erase well if you use fine quality paper. It does not erase well on cheap paper. I suggest if you are using these to sketch you use Moleskine Sketchbooks which use a heavier paper than most brands.I use this color a lot and I mean A LOT when I sketch. It is helpful when I am laying down a foundation for character work in my sketchbook. Now that I own it I can't see myself not using it. I can't believe more brands aren't mimicking this color lead thing. :)I was able to find blue Pentell lead on another site, I wish Amazon carried it.
