Fuxi
A 9 x 12 inch top-spiral sketchbook with 100 micro-perforated sheets of 100gsm bright white paper. Its diagonal tooth grips graphite, colored pencil and charcoal.
Best for: Students and daily sketchers practicing with pencil and charcoal
The Fuxi 9x12 Spiral Sketchbook is a 100-sheet pad of bright white, acid-free drawing paper, bound at the top with a coil and protected by rigid front and back covers. Each sheet is micro-perforated, so it tears out at a full 9 x 12 inches.
The paper is 100 gsm (68 lb) with a light diagonal tooth that grips graphite, colored pencil and charcoal. Fuxi says the surface sizing stands up to repeated erasing, which makes it a practice pad you can work into again and again. It is made for dry media, not paint or alcohol markers.
Based on the manufacturer's Amazon listing.
Fuxi lists graphite, colored pencil, charcoal, pens, light ink and oil pastels, on 155 micron thick sheets.
Fuxi says the diagonal tooth grips graphite, colored pencil and charcoal for clean lines, shading and blending, and the sized surface withstands repeated erasing during figure and still-life studies.
The coil sits above the page, which Fuxi says reduces wrist contact for left- and right-handed users, and the pad opens flat while you draw.
Pages tear out cleanly at a full 9 x 12 inches, ready to hand in as homework, share or frame.
Firm front and back boards protect the pages in a backpack and give you a stiff surface to draw on in class, outdoors or on your lap.
Acid-free pages help reduce yellowing over time, and the bright white keeps pencil lines and color clear.
Look elsewhere if: you want to add ink or watercolor washes. The MOFUNY Mixed Media Sketchbook 9x12 uses heavier 160 gsm paper and is listed for watercolor washes and layering.
