Now available in pads, Arches Oil Paper is "ready to use" without the need for any prior preparation. Specifically designed for oil painting, this durable 100% cotton, acid-free, 140 lb (300 gsm) paper features a fine grain, tough NOT surface that absorbs water and solvents, allowing the paint and pigment to remain on the surface for a vibrant effect. This is perfect for withstanding vigorous painting techniques like rubbing and scraping, and is heavy enough to support impasto layers. Available in a 23 x 31cm size and contains 12 sheets.
