For the price a good learning kit
This is a good teaching kit for a child that is interested about codes and passing information back and forth. It does lack the information about when cyphers were used and for what. I did gift it with a book about spies during the revolutionary war.

Smaller than expected
This came and was much smaller than expected. My daughter received it for Christmas and was excited, we will see how it holds up!

decent but underwhelming
This review is for the Thames & Kosmos Spy Labs Inc: Secret Codes and Ciphers, Learn how to make and decipher four types of secret codes. I love that this comes in a metal tin to store the spy tools. The kit itself is a little underwhelming. It includes a small direction insert, cardstock pieces for a cipher disk and polybius square, a piece of rope for Quipu (knotted codes), and chalk to leave vagabond messages. The knots and chalk are more of a suggestion for kids to create their own secret spy code. Overall the box is fantastic and the kit is good but not what I expected. The pieces are flimsy and some of the code methods are much more simple than expected. Despite my underwhelm I think that my kid will have some fun with it and will enjoy using the tin to store treasures in when he’s done with the coding tools.
