Pencil types

well I know B means black and I don't know what F means but H means hard, numbers are how much they are H or B

F is fine. But the combo of HB2 is an odd one because it mixes hard and black.

I would guess it is right smack dab in the middle but I will see un momento por favor

HB2 is the most standard shade, most of your writing pencils are probably HB2 unless they say otherwise
