Tin Woodman's Heart is a mechanical box which is satisfying to hold and beautiful to display. It comes with a lock and resettable combination key. The key to open the box is a sentence combined out of 3 words, which can be changed. You can make it romantic and set the key to "I love you" or you can set it to a fun message e.g. "I love beer". There are 8 words on each of the 3 wheels and you can use the possible combinations and set the key sentence that suits you the best. It's a great gift wrap to hide a secret message or a small present.
