Available in hardbound, wirebound, and softcover formats, these sketchbooks contain multiple sheets of 100 lb (150 gsm) natural white paper with a vellum surface and a distinctive tooth. Ideal for dry media and light washes, the paper is both internally sized and surface-sized. It has remarkable wet strength and wet media can be lifted after drying without damaging the surface. Pigments are not absorbed deep into the paper, so colors remain exceptionally vibrant. The hardbound sketchbooks contain 62 sheets (124 pages) of paper. The wirebound sketchbooks contain 50 sheets (100 pages) of paper. The softcover sketchbooks contain 46 sheets (92 pages) of paper.
