I now have refillable hardback sketchbooks that have blank pages and are ideal for sketching and drawing. The pages are lightly textured and acid-free and are great for pencil, pen, pastel, charcoal, and other dry media. They each have 110 pages and are 70 lb (or 110 GSM). These refillable sketchbooks come in four sizes (two are horizontal): 8.5 x 11, 11 x 8, 9 x 6, and 4 x 6 inches. The refills will be available on my website.
