Our popular Super Deluxe Decoder in a lapel pin / tie tac. This utlra cool stainless steel pin 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 below the secret window to swap with the letter on the perimeter of the disk. Unscramble your message using the reverse technique. A great gift for aspiring sleuths, pen pals, significant others.
