Roy Fine Art stretched canvases are made with a high-quality, acid-free, 100% cotton, medium grain canvas, and professional stretcher bars for improved strength and optimal stability. The canvases have been given three coats of acrylic titanium; triple-priming creates a perfect ready-to-use painting surface for both oils and acrylics. This holds the colour on the surface and prevents seepage through to the back. The canvases are stapled on the back to give clean edges and are individually wrapped to protect the surface.
