The Pentalic Recycled drawing Book is lightweight, portable, and easy to take along as a journal or sketchbook. Manufactured of acid free, natural white, recycled, 86 lb. (140 gsm) paper, this European style sketchbook contains 40 versatile pages excellent for drawing and sketching, as well as light use of wet media. The saddle stitched binding is unobtrusive, allowing sheets to lay flat. If desired, the artist can draw across the page, doubling the surface area of the sketch book! This recycled, 30 percent pcw paper is manufactured in the U.S. as is the brown kraft cover.
