The exterior of the hardback Bamboo Sketch Book features an artistic bamboo cane design, while the interior paper is composed of 90% bamboo fibers and 10% cotton rag. The use of bamboo makes this sketchbook a more environmentally-friendly choice for paper production. Its natural white sketch paper boasts a distinctive tooth surface that allows for exceptional color retention when using pencils, charcoal, and chalk. The bamboo Sketch Book is both acid-free and highly resistant to age.
