Why didn’t we have this stuff when I was a kid? Sure, we had Etch A Sketch and Lite-Brite, but kids today have all kinds of cool stuff, like this LED Illuminated Message Board. It’s like a dry erase board. With the appropriate pens you can draw whatever you want on the white display.
After that just hit the switch and the whole thing lights up like a psychedelic chalkboard. That’s sure to get your message across. It can be written on over and over again and will display the colors red, blue, or green.
