033: Sustainable-ness

The back of a notebook bought at the Target:

Our pages are made from 100% post-consumer waste with nontoxic soy-based ink.

The notebooks are called greenroom eco...very design orientated and markers (Prismacolor, Copic) do not bleed through. Which is very surprising, considering my main archisketchbook is a Moleskin Sketchbook, which costs a lot more, but all markers bleed through it.
