Staedtler Non-Photo Blue Pencil

This non-photo blue pencil is an essential tool for cartoonists, illustrators and graphic designers. This pencil produces a blue line that is easy to see while you are working but disappears when you are ready to move on to the next layer of your project. Instead of having to erase your graphite underdrawing or sketches, the blue pencil marks vanish when photocopied, reproduced or microfilmed.
