Secret Agent Spy Pens

A fun gift that budding secret agents can use to write messages which can only be seen under the pen's UV light.

Includes two pens, with hidden UV light in lid. Each pen uses 3 LR41 Lithium batteries which can be replaced by unscrewing the pen lid.

How to use:
- Step 1: Write a secret message
- Step 2: Use the secret lamp in the pen lid to read the message

Warning:

• Button batteries are easily swallowed and can cause serious harm.
• Check battery cover is secured correctly before use.
• Keep batteries away from children.
