WARNING: Comic talk ahead! I wanted to write a short review of the 'non-photo' blue pencils I have been using lately. I'm doing this so that if you have to order these things through the mail or don't want to waste money trying and buying these things then hopefully this review will point you in the right direction. There are three pencils that I have come across. There are other types and brands, but these are the ones I have had experience with and I think may be the most commonly used in comics. 1-Sanford col-erase non-photo blue. (pictured) This pencil's lead is quite hard and hardly shows up on the paper. This is good if you only want faint marks as guidelines and not so much an actual finished drawing. There is an eraser on the end that actually works to a certain degree. Although it's really only for peace of mind as you don't need to erase the pencil after inking anyway. I found this pencil too light to do actual finished or rough outlined
