imSTONE A6 Sketchbook. Environmentally Friendly, Waterproof Drawing Notebook. 60 Pages 4 1/8” x 5 13/16”. Recycled Paper Made from Stone. Super-Smooth Blank Pages with Venice Cover Design

I used micron ink pens for drawing on this surface. It smudged, bled and feathered. It is completely unusable. I also had ink transfer to my hands as I was drawing. I don’t like this paper at all. I was looking for a substitute for Terraskin (which I can no longer find) and this did not work.

Nice pocket sketchbook. Good paper.
