Tombow Mono-WX Pencil Lead - 0.5 mm - HBB

My favorite graphite.
Excellent design and it has two openings, one for taking out one stick out of package and another opening to take a few sticks at the same time.

To me this lead is the first to actually beat ain lead in a strength test and I was really surprised. I recommend buying this lead a LOT.

Very light gray and hard on the paper, It is almost if it were a harder H grade lead, which means that maybe the B grades are more suitable and softer for common writing tasks.

The case is very nice, the cap is not removable but slides at both sides, to one side it delivers only one lead at a time, and to the other side a group of leads. I think is my favorite case, sadly, not my favorite lead.

oooooo why wont they make these in 0.7 mm???
