Trying out a new sketch book by Crescent called RENDR with a backwards R at the end.
It states "no bleed through" on the cover.
Some of the pens that I used: Tombow, Faber-Castell brush pens, Prismacolor Premier Fine Line, and Sharpie fine line.
There was no bleed through to the other side of the page but when I added water with a brush to the Tombow (blue in the picture) the paper started to buckle and then disintegrate!
More experimenting to come! Someone suggested putting gesso on the page.
