This is a very collectable packing puzzle by William Strijbos. I have had it since the 1990's. Very fun to solve. The pictures are from John Rausch's website under craftsmen, William Strijbos. I know the buyer will be very happy with this one. It's made from precision cut galvanized steel. It's very heavy for it's size. It is as new because it has been packaged and stored with other collectables.Shipping will be $10.00 for the U.S.A. and $25.00 International Shipping.

This puzzle is a groundbreaking and highly anticipated design. Only 30 copies have ever been made in the past, and Brian at Mr. Puzzle sold them out very quicky. The Ternary burr consists of 22 pieces, with over 90 notches and and grooves. The unique solution requires 75 moves to get the first piece out, and over 90 moves to completely disassemble the puzzle. A very difficult work of art!Here is what the designer, Pit, has to say about it: "One evening, I was playing with Bill Cutler’s Binary ...

(made from 1/8" thick laser cut plastic, board 2 layers, pieces 1 layer, 3.6" x 5.6" x 1/4") A puzzle with many pieces and much white space. The solution sheet that comes with the puzzle shows a 105 basic steps, many of which are composed of several rectilinear moves where some require two pieces to slide together; here a 12 of those positions:

(made from 1/8" thick laser cut plastic, board 2 layers, pieces 2 layers, 4.375" x 4" x 3/8"; the eight pieces are two layers only due to the dog ears) The start position has the two dogs facing away from each other and the other 6 pieces neatly arranged above them. A natural problem is to exchange the two dogs while leaving the rest of the puzzle the same. A second problem, shown in the puzzle directions and sample solution, is where one of the square pieces ends up above the do...

Boron is not necessarily trivial but also not mind-bendingly difficult. The four inch size has a nice heft, weighing in at a full one lb. weight. This is a great gift for someone you want to encourage spatial abilities without them getting too frustrated.Construction is very good, precise but with a tiny bit of extra room to compensate for very dry shop conditions.

This box has some minor scratches on the top and bottom faces. These faces are also a little shiny from skin oils from trying to move them.

Together with the Begonia, Core is a unique and interesting puzzle that is both a packing puzzle and an interlocking puzzle. Eric Fuller so aptly described the Core in the following (excerpt from CubicDissection): When I saw this design (along with "Begonia") I knew immediately I wanted to make it. Blurring the line between a packing puzzle and an interlocking puzzle, the goal is to construct the 3x3 cube inside the box. Tougher than you might imagine since the opening is only 2x2. The solver mu...

Exchange puzzle for IPP22. Solution included.

Original Mechanism Box '98 as created by designer Atsushi Katagiri and craftsman Hideto Sato of Karakuri Creation Group for IPP 18. Has unique 5 move opening mechanism. Note that the mechanism on this box is extremely tight, making opening laborious. It needs significant working in, possibly a drier climate. For this reason I am offering the box with a very low starting price. Other than the extreme tightness the box is in as new condition. Measures 4 3/4" x 3 1/8" x 2 3/8" (12cm x 8cm x 6cm). ...
