Let's talk about the brushed H B. What are they used for?

HB is generally used for tricks, because it is hard to draw deep, and 2B-3B is generally used for painting the front. All the other doors are made of hard pen 4B, so you can use it for tuning. B number is softer, and B number can be darker, which can speed up your painting process. 5B- 12B See if you need to choose a dark pen.
