Kunst & Papier Binderboard Sketchbooks are some of the most in-demand sketchbooks we carry! They are made in Germany and feature sturdy binderboard covers that can be bound with with bookcloth, fabric, or paper, or decorated however you like. They can be opened flat and even bent back double without damage to the binding. The heavyweight acid-free pages are great for all dry media as well as water-based markers, inks, and light washes. You will love these sketchbooks!
