Spy Pen


The Spy Pen is the perfect gift for that budding spy in your life. With it, you can write secret messages that only your fellow spies can decode.

Invisible ink, when dry, appears as if it were blank, with a similar texture and reflectivity as the surrounding surface. The ink can then be later made visible by viewing under ultraviolet light.

Warning: Not suitable for children under 3 years of age as small parts may present a choking hazard.
