Our Cass Art Watercolour Spiral Pads are part of our award-winning own-brand range of papers, which give you dependably high quality and excellent value for money. Our watercolour paper is acid-free for added longevity, and cold-pressed, so it's slightly textured. Each spiral pad contains 12 sheets of good-quality 300gsm watercolour paper. Cass Art Watercolour Spiral Pads come in two sizes - A3 and A4.
