Both faces of the board erase with a dry cloth, so chalk dust and marker lines come off without a spray bottle. A chalkboard on one side and a magnetic whiteboard on the other mean two children work simultaneously rather than trading turns. A 16.4-ft paper roll 12 in wide feeds down the front as a third surface and swaps out when it runs low. The frame stands 42 in tall on an A-shaped MDF and pine base, and it collapses when the drawing is done. Meets ASTM and CPSIA for ages 3 and up.
