Give your notes and sketches a new dimension! Simply draw on this pad and then look at your drawing through the included 3D specs. The specially printed (stereoscopic)graph creates the illusion of depth. The best effect is achieved using black ink or very dark colors. Pad measures 5-3/4×8-1/4 inches; the 3D graph on each sheet measures 4-1/2×7 inches. 50 sheets of paper and 3D specs included.
