I had made this puzzle a long time ago, maybe in the 2007. I sketched it from a design and then cut it with wood. I still keep the mark from the pen.

This puzzle has 12 pieces, which 1 of them is the key piece, please refer to picture number 2. The goal for this puzzle is to unlock it to take the inside, and then assemble it to the first shape. It was fun to play and a great way to give some one a small valuable gift, such as engagement ring

please also let me know how to align the photo in the center, it is not ver attracitive when aligning in the left
