Strathmore(411-9 400 Series Layout Bond Pad, 9"x12", 50 Sheets

Does this paper work well with pencil and/or charcoal?

Does ink smear on the tracing paper part?

What exactly is this paper used for? it looks like tracing paper over another, thicker paper. why not just use tracing paper? what am i missing here?

will prismacolor markers bleed through the paper?
