My first metal puzzle box; I'm happy with how it turned out! This box has a very minimalist look with a plain brushed aluminum exterior. The mechanism is completely hidden; even with the box open you can not see the workings. The box has two solutions; one moderately difficult and the other very difficult. The first solution can be discovered using gravity (among other things). This is the easier solution. Once that is discovered, I challange the solver to open the box without picking it up. As small as it is, this box is quite heavy, and will not be mistaken for a mass produced work. It has heft and the hallmarks of hand craftsmanship. Each box is signed and dated; 21 were made for sale.
