This Artist Series cold-pressed watercolor paper features a natural white appearance that provides excellent color representation and stability. The 140 lb. (300 gsm) paper is sized in the pulp for exceptional surface strength to withstand repeated washes and allow you to easily make corrections, even with a simple brush stroke. The sturdy surface and ability to lift colors makes it ideal for learning and experimenting with watercolor techniques. This high-quality paper is acid-free, buffered, resistant to mildew and produced without optical brightness additives. Their strong performance makes these sheets suitable for all wet media including watercolor, acrylic, and gouache, but they may also serve as a slightly textured substrate for pencil drawings.
