Ultraviolet Spy Pen by Accoutrements
Pretend you're an international super spy on an undercover operation to save the world from an evil maniac with plans to take over the world with a solar-powered satellite laser gun. What is the one accessory you'd need most? The Spy Pen, of course! Each 5" (12.7 cm) long plastic spy pen features ink that is made of special high-brightness compounds that are invisible to the naked eye, but magically illuminate when exposed to ultraviolet light. A blacklight is conveniently located on the opposite end of the pen, allowing you to read any messages left to you by your spy friends. Perfect for writing down secret spy messages, scrawling secret grocery lists, or keeping a catalogue of all of your Internet passwords. Batteries included.
