With the Secret Decoder kit you can write and reveal invisible messages, uncover hidden clues and crack codes! Perfect for spies and secret agents.
We use good quality gender-neutral wrapping paper. As a default, all orders placed in November and December are wrapped in Christmas wrapping paper, and all orders placed in other months are wrapped using a non-Christmas paper (eg for a birthday). If you prefer birthday paper in the run up to Christmas or Christmas paper at other times of the year, you can request this in the Special Requirements box on the Basket page.
The Secret Decoder Deluxe Activity Set is the perfect kit to learn the tricks of the super sleuth trade! Crack the codes and complete the puzzles to solve dozens of mini mysteries! Figure out whodunit.... then turn the page for a whole new mystery. The spy kit contains:
With over 50 activities there's plenty to keep spies, sleuths and secret agents busy for hours!
