Do you like enigmas and challenges or do you have a significant other who does? Then, spend a minute reading about the Da Vinci Code Locker. This is a good gift for birthday or even the Valentine’s Day. The default password of the thing is I LOVE YOU. However, you are free to set your own.
You can put inside a little personal secret (or a gift), close the box and set a new password that is related to your relationship. The other person will have to guess it using the two rings on the side of the box to change letters. This present is simply adorable and could be a fun way to give something more significant such as a necklace.
