How the Spy Coin works:
Hollow coins can be used to carry secret messages undetected and can very easily be passed to a recipient. They are absolutely indistinguishable from a solid coin to the naked eye.
They can be safely handled without danger of separation and can easily circulate without leaving a trail. Just carry it in your pocket with the rest of your change!
Uses a standard paper clip (not included) to make a "key" to open your coin.
WARNING: Small parts. Not for children under 3 years
