I stored these in a bag after purchase. I don't know how many sheets were originally included, so I'm listing them as "like new." I'm unsure if they've been used. There are 20 sheets. They are generally in good condition, but the cover has a slight dent. Please check the photos. These are "Art Spiral" sketchbooks, popular for their colorful covers and versatile use. - Features a two-tone color wire that matches the cover. - Colorful and durable PP-wrapped cover. - Made with neutral pH paper for excellent preservation. - The thick drawing paper is the most textured and widely used. The paper's texture (surface irregularities) is created with woven felt, resulting in a natural and painterly effect. It's soft and highly absorbent, making it suitable for watercolors. It's also high-quality drawing paper that can be used with pencils, crayons, pastels, and more. The surface is strong and resists pilling when using an eraser. Also made with neutral pH paper for good preservation. The thick paper has the most pronounced texture and is widely used.
