A single square foot of our Kryptonite sheet.
Use a white, blue, purple, or ultraviolet
LED to write on this material, and watch it
slowly fade over the next hour or more.
Draw pictures, write messages, play games, the
glow is the longest lasting of any material known to man.
With a purple or blue laser, you can write on it from
several feet away.
Use a camera flash or strobe light to make shadow images.
Or, cut out letters from it to form glow in the dark signs,
such as EXIT signs, or arrows to indicate directions, or make
stairs visible after the lights go out.
Comes with a self-stick coating on the back.
