I designed and made this box for a friend who used it to propose to his girlfreind. It is 2″ x 2″ and made of zebra wood and purple heart. In the front is a lock made of all internal wood parts. When turned a quarter turn the lock moves a piston up into the top of the box to secure it. The ring was placed around the square wood peg in the middle. It was nice to throw some wood shavings around like I used to.
