The Mirado black warriors are fairly good pencils, no. 2, HB and all that. They definitely write better than your run of the mill pencil, but I think I prefer the USA gold pencils because they write darker. For the blackwings: these pencils have quite a history. They used to be made by a different company and were the favorite tool of many artists, writers, and musicians. The Palomino company started making them again not to long ago, but some people say they aren't quite up to the standard of the old ones. The blackwing comes in three different varieties, regular which writes dark, 602 which writes lighter, and the new pearl which is somewhere in between. Palomino also makes some other pencils I'm interested in. But all of these pencils, other than the USA gold and black warrior, are very expensive, between $1 and $2 per pencil.
