These canvases from Bob Ross come in a pack of 2 and feature a medium smooth surface perfect for painting on. Each canvas has been double-primed with a grey primer, allowing the painter to see if the liquid white is properly applied. The canvases come pre-stretched much tighter than other brands, giving you more durability especially when tapping and painting the surface with large brushes or painting knives. These canvases measure 30cm by 40cm. - Brand: Bob Ross - Size: 30cm x 40cm - Pack of 2 - Medium smooth surface - Pre-stretched extra tight - Double primed
