Programmable Message Digital Pen

It can write like any other pen great for doodling, shopping lists, writing your memoirs, whatever but you can also create up to four of your own glow in the dark messages. When you wave the pen back and forth, the LED lights display your message as if it were floating in air! You can select from 64 characters to create and save your messages. Runs on three AG13 batteries (included). Great fun for parties, sports events, and concerts.
