The Tombow Mono-RS is a graphite lead pencil available here in either 2H, HB or 2B lead grades.
2B is softer than both of the lead grades above. It has a high quantity of graphite and so produces a much blacker line than the other leads. Because of this, the point does wear down a bit more easily and you will need to sharpen this a bit more often. 2B is a great drawing pencil for illustration and shading.
USES: 2B is great for illustration
