This Studio White Stretched Canvas is made of 100% cotton canvas with medium grain texture, which holds paints well and keeps the paints with their natural tones and glossiness. The acrylic triple primed acid free canvas creates a non-yellowing surface and makes the painting surface ready to paint, collage, draw, sketch and illustrate with excellent tinting strength, which works great with acrylic and oil paints by amateurs & beginners. Standard sizes for easy framing and hanging on the wall. Wood structures with mortise and tenon connection ensures the frames firm and sturdy. Canvases are stretched tightly onto the bars and back stapled to create clean edges. Multi-pieces per pack is more value than single package. This is vendor labelling and studio grade.
