Rikagaku KittoPass Kids Smooth Surface Wet-Erase Magic Crayon - 12 Color Set

These 2009 ISOT award-winning crayons are delightfully innovative because with them you can create a whiteboard out of practically any smooth surface. They can be used on paper like traditional crayons as well as on untraditional surfaces such as glass, plastic, bathtubs, whiteboards (not blackboards) and more. The “magic” crayons can easily be erased from non-porous surfaces with an ordinary wet cloth (always test first) and are made from kid and environment friendly material consisting mainly of paraffin.
