Unit price per 

This secret decoder pin is a working vintage-style brass cipher pin for holiday fans, puzzle lovers, and collectors, perfect as a nostalgic stocking stuffer or a fun way to send coded messages.

Long before text messages, the most exciting thing a kid could find in the mailbox was a secret decoder of their very own. This brass pin brings back that old-fashioned thrill. Its two rings spin independently, so you can match any number to any letter and create a code only your closest friends can crack. Inspired by a holiday classic and the radio-era mail-away premiums that sparked so many young imaginations, it's a small treasure with a big dose of nostalgia.
