The GLOWPAD Studio features three drawing functions! Slide a picture under the screen to trace, angle the pad to copy any 3D object, or simply create your own drawings and doodles. The pens clip neatly into the pen holder section and there's a fold-over protective cover so you can take it anywhere you go. Once you've created your drawing, press the button to light it up with 1 of 7 LED effects! Requires 3 x AAA
