A high quality precision device designed to tightly stretch watercolor paper. As the screws on the edge of the board are tightened, tension is placed on the outside edges of the paper. After the paper has dried, the paper will stay flat and buckle-free during wet washes. A unique feature of the Watercolorboard™ is the beautiful embossed edge it leaves from the frame tightening on the paper. Holds 90 lb., 140 lb. or 300 lb. paper. Includes a universal tripod mount on base, which allows you to attach this set-up to a tripod, and a comfortable carrying handle.
