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.
If you like Tombow wooden pencils, then you will love these leads. The lead is
nice and smooth, strong, and dark. The HBB is just a hair darker than the HHB
or a standard HB and has the same smooth feel that I have come to expect from
Tombow's wood pencils. The box looks nice and comes with two openings, so you
can pour out several leads or just one. Tombow HBB are top notch leads.
