Cool detective set in a high-quality metal case. Recommended for ages 8 and up. Includes a DIY decoding disc, cipher boards, a string for knot language, and a piece of chalk for marking. With this set, secret messages can be encoded using various encryption systems. Children can send texts that are incomprehensible to others using the coding disc and cipher board. The instructions clearly explain how to alter texts and make them unreadable to others.

Just like Justus, Peter, and Bob from Rocky Beach, boys and girls aged 7 and up can encrypt every important message. Only certain individuals are allowed to know the secret contained in the message. For others, the symbols are completely incomprehensible. To assist children in this detective toy, various tools such as the coding disc and cipher board are available. Conveniently, the gadget is always within reach in the small metal case.
