This utlra cool stainless steel ring uses a substitution cipher, where one letter of the alphabet is switched for another. The message: "Look in the secret chamber" would be scrambled to read something like: "Kjde je nes kelzd meilfha" You spin the outer disk, using the letter inside the secret window to swap with the letter below on the inner disk. Unscramble your message using the reverse technique. A great gift for aspiring sleuths, pen pals, significant others. Also very motivating for children learning to read and write.
