Soucolor
A 9 x 12 inch, 100-sheet drawing pad of acid-free 68 lb (100 gsm) paper, top spiral bound so it lies flat, with micro-perforated pages.
Best for: Kids and students who draw every day or need a pad for art homework
The Soucolor 9x12 Sketchbook is a 100-sheet drawing pad of natural white, acid-free paper, bound at the top with a spiral. It opens flat, the pages are micro-perforated, and a sturdy backboard and cardstock cover hold it together.
The paper is 100 gsm (68 lb) and pH neutral, made for pencils, pens, crayons, charcoal, pastels and sketching sticks. Soucolor is clear that it is dry media paper, and points marker and watercolor users to its dedicated pads instead.
Based on the manufacturer's Amazon listing.
A standard sketch weight in a pad big enough to last a young artist months of daily drawing.
Soucolor rates the paper acid-free and pH neutral, which helps artwork keep its quality over the years.
Pages flip easily and the pad sits flat when open, which suits both left- and right-handed users.
Each sheet tears out on its own, so a single drawing can be handed in or put on the fridge.
The sturdy back and thick cover keep the paper in good condition and give you something firm to draw on.
It fits in most school backpacks, art bags and large purses for class, field trips and long car rides.
Look elsewhere if: you want hard covers to draw on without a table. The Fuxi 9x12 Spiral Sketchbook has the same paper weight with rigid covers.
