Eric Fuller made a run of Buttonhole puzzles a few years back; this is one of them in Ambrosia Maple.

Secret Box 1, 2, 3, and 4. I'm not sure who makes these; there's a label on the back covering up some info, and I'm reluctant to peel it off. Anyway, these look fairly nice; they're made from high-grade plywood that appears to be laser-cut and stained. There's a tiny chip on the edge of the end of box #4. You can get these fairly cheap from a number of sources right now, or you can just buy them here. The mechanisms are fairly interesting, which surprised me, including a gravity-mechanism that d...

Custom internal mechanisms were hand milled from solid bar stock aluminum and took several weeks alone to make. Each 51 Pound Puzzle Box is signed and dated by the artist. This box does contain powerfull magnets, and as such should be kept away from mechanical watches, credit cards, sensitive electronic equipment and pacemakers. For obvous...

Although it looks relatively modest on the outside, this is a phenomenally difficult puzzle box to open. It is by far the most difficult box Eric Fuller has produced for the public. T Beginning with simple sliding panel moves, the solvers task is to find the key and use it to disengage the concealed locks which prevent it from opening further. Once again, the simple appearance of this box belies the amount of work poured into its craftsmanship and construction. It is a very, very difficult puzz...

Binary Burr by Eric Fuller. His original comments: The Binary Burr is a classic Bill Cutler design. It was awarded a First Prize at the 2003 IPP Puzzle Design Competition, and has been unavailable for several years. Here is what Bill has to say about it: "The Binary Burr is a burr that functions like a 6-ring version of the Chinese Rings. The puzzle consists of 21 pieces. One is equivalent to the ‘bar’ in a Chinese Rings puzzle, and six others are equivalent to the ‘rings’. The other ...
