Although the mine appear quite thick at first glance, but can be fine strokes pull it, so you can really fine with the "Easy Graph HB (2 1/2)" writing and drawing. In addition, the mine is likely (but not too) soft, so achieving good results also learning to write with this pen.
There are even two different versions of "Easy Graph HB"; one for left (yellow) and the other for right (red mark). Since I'm right-handed, and even those very version got, seem to me the pencil and use of "normal". What is the difference to the other version, I can not judge.
Another quality: The pencils do not break constantly from the sharpening. So you have a little time of each single and of the entire package.
