This is a set of 12 unsharpened pencils in a plastic case.
About pencil hardness grades:
A greater percentage of clay results in a harder pencil lead, and lead is graded by hardness. Pencils graded H, F, HB and B are of average hardness. Pencils ranging from 2B to 10B are softer and are used for sketching, while 2H to 10H pencils are harder than average. A common American #2 pencil is equivalent to an HB pencil.
These are the lead grades from hardest to softest:
10H | 9H | 8H | 7H | 6H | 5H | 4H | 3H | 2H | H | F | HB | B | 2B | 3B | 4B | 5B | 6B | 7B | 8B | 9B | 10B.
The harder the pencil the lighter the mark, and the softer B-grade leads tend to create darker colors and smear easily.
