The Artograph Animation Disc is a convenient way to convert any light box into an animation work center. The 14" (35.6cm) 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.
