The MOFUNY Mixed Media Sketchbook 9x12 is a ring-bound pad of 60 sheets of 160 gsm (98 lb) mixed media paper. Hard cardboard covers protect your work, and the listing says the pad can be rotated 360 degrees.
MOFUNY says the paper is thick enough to keep ink from bleeding through the pages. The listing names pencil, pen, charcoal, crayons, sketching sticks and gel pens, and also describes it handling watercolor washes, gouache and acrylic.
Based on the manufacturer's Amazon listing.
Heavier paper is generally better at taking wetter media, and MOFUNY says ink does not bleed through the pages.
MOFUNY describes each sheet as acid-free, which helps keep colors from deteriorating or fading.
The listing says the pad rotates 360 degrees to give you the most drawing space, and that the ring binding protects pages as you turn them.
MOFUNY says the hard cardboard cover and back protect your drawings and are not easy to damage.
The listing names pencil, pen, charcoal, crayon, sketching sticks and gel pen, plus watercolor washes, gouache and acrylic.
A roomy standard size that still tucks into a bag or backpack.
Look elsewhere if: you want heavier paper in a hardcover and do not mind a smaller page. The String & Space 200gsm Hardcover Sketchbook lists 200 gsm paper for charcoal, colored pencil, oil pastel and watercolor at 5.8 x 8.5 in.
