Pencil Lead Hardness (from Wikipedia)

Pencil lead is graded by hardness: a greater percentage of clay results in a harder lead. H (harder), F, HB and B (softer) are pencils of average hardness. Pencils ranging from 2B to 9B are softer still and are used for sketching; 2H to 9H are harder than average. A common American #2 pencil is equivalent to HB.

In order, the leads are (from hardest to softest) 9H | 8H | 7H | 6H | 5H | 4H | 3H | 2H | H | F | HB | B | 2B | 3B | 4B | 5B | 6B | 7B | 8B | 9B.

The harder the pencil the lighter the mark, e.g. Bs tend to a create darker colour that can be smeared easily.

I really like the darkness...
April 29, 2011
I really like the darkness of this lead. I use it in many of my Pilot, Uni, and Pentel technical pencils. The lead is durable for it's softness and can be used well with any pencil. Of course, people who write heavy handed will be advancing the lead every few words! The lead does smear quite easily, but also erases almost completely using a white eraser. All in all a good investment.

I've been looking for dark leads for a while. I will never switch back to regular lead again. I love the fact that it's dark, soft, doesn't break, doesn't smudge. It's most definitely worth it! Great, great product!
Darkest grade of lead...
April 13, 2014
Darkest grade of lead you'll find for mechanical pencils on here. The lines give you almost a 7B-8B darkness. The lead is smooth, of coarse easy to blend, and never had any breakage problems. (I use Pilot mechanical pencils mostly). Supper great and the function of the case itself is great to keep it from breaking into pieces. Love it.

I didn't like the choose of color for this but....
Very smooth, easily smudged, and dark! Just like I want it.
The case can be flimsy sometimes though.
Overall, good choice for lead.
