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.
This is seriously good pencil lead. It's super smooth, fast, and dark. This and
the Hi-Uni are, in my opinion, the best leads available here. It's also at least
as strong as any other lead that I've tried (I don't really break leads no
matter how cheap they are, so I can't comment on strength.)
I've tried most every lead on Jetpens and if I had to choose only one brand, it
would probably be this one. Hi-Uni is a very close second, and maybe even just
as good, but that's more subjective than anything.
