The Monet Pro Monterey stretched canvas is a 7 ounce cotton canvas, sized and double-primed with archival quality acrylic gesso for a medium tooth resulting in a final weight of 10.5 ounces per square yard.. Perfect for artists who want a staple free canvas. Edges are 1.5 inches deep and staple-free so you can easily remove the canvas and re-stretch it on the same size frame. The MuseumWrap stretching system offers the tightest stretch possible, with tongue-and-groove corners and no finger joints. Made with solid pine or fir stretcher bars.
