This is a puzzle box I built for my girlfriend for Christmas. It was made by hand and is my own design. She loved it! The box is composed of three 1/8" layers. The inner layer is the basic shape, the intermediate layer houses every sliding/locking/rotating/puzzle component, and the outer layer is to make it look nice. Though I get many requests, I made this as a special gift for a special girl so I don't make them to sell.
