This product contains 40 pieces of high strength, high-quality Tombow Mono-WX Pencil Lead. The lead has excellent core strength, smooth performance, and is available in multiple lead hardness grades. The top of the unique dispenser opens to the right to dispense a single piece of lead at a time, or can be pushed to the left to extract multiple lead pieces at a time.
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.
