The Winsor & Newton Classic canvas (40cm x 60cm) is made of cotton and is used for oil, alkyd and acrylic paint. Thanks to the excellent pre-treatment of the canvas, the paint adheres excellently. These cloths are acid-free and archival. The wooden slats are produced according to high environmental standards and have a thickness of 2cm. The canvas is stapled to the back, so the sides can also be painted.
