Regular price $6.00 $6.00
Part of our “Super Secret Spy” range, this clever spy pen lets you write secret messages only revealed by the built in U.V. light! Perfect for any budding spy. Write with one end of the pen on a piece of paper. To the normal eye it will look like a blank piece of paper, then use the other end of the pen to shine the UV pen on it and the secret message is revealed. Pens sold individually.
