These last drawings are in a Barnes Noble sketchbook. There are 60 sheets and the paper feels like cardstock weight and they're archival too. They come in different sizes, landscape and portrait with 2 very stiff board covers. They come in different sizes and even have one that has kraft papers instead of white and the pages are perforated. This one is 8.5 x 5.25. I draw on both sides. If I mess a page up I just glue some blank paper over it.
