The Artograph® Animation Disc is a convenient way to convert any light box into an animation work center. The 14" (35.6 cm) diameter revolving work surface can be fitted with either of the two enclosed peg bars; the industry standard Acme peg bar or the round peg bar for mounting common 3 hole punched copy paper. Disc mounts onto any flat illuminated surface (not included). Non-slip foot pads included.
