Review on 🎃 EODVICS Invisible Message Halloween Christmas: Unmask the Cryptic Surprises! by Kirsten Duncan

This toy is perfect for little spies who want to leave secret messages around the house. The invisible ink is easy to write with and the UV light makes it fun to read. The small size of the pen makes it easy to hide in your pocket for secret missions. The only con is that the ink can be a little difficult to see without the UV light. Overall, a great addition to any spy kit in Toys and Games.
