This copy of the Pentagon box is one of the better B&M puzzles made. It's 5 years old and while it's tightened up a bit, it still works fine.

This was held over from my personal collection, and is a unique wood combination (the ones sold on the website were solid in color).From Mr. Cutler's website: "I had always been interested in designing burr puzzles which are difficult to take apart. The burr shapes I had used to this point all had the same symmetry as the 6-piece burr or the 24-piece burr - mathematically there are 24 symmetries to these shapes. However, keeping all these symmetries and creating a new shape resulted in...

from mrpuzzle.co.au:The object of the puzzle is find the T inside the Boston Tea Chest.You will have to disassemble the burr to find it. Brian got the idea behind this puzzle from an old Phillipe Dubois puzzle. The T shaped pieces were originally two sets of mirror reversed triplets. He changed these pieces to ensure they were all different, giving it a unique solution, now separating on one axis only. Brian also added a locking mechanism that will ensure the puzzle is more difficult to disasse...

This japanese puzzle box is 5.5 inches in diameter, and was made more than 5 years ago. It is in excellent condition. However, it does have some very light scratch-like dents. They can barely be seen or felt with fingertips.The original Kamei sells for over $1000, so this is a great opportunity to get his puzzle!This reproduction is such a good copy! I was very impressed with the quality of the craftmanship for this box. I think other collectors who do not want to pay a thousand dollars for...

This is a reproduction of an OLD Kamei puzzle box is 6 inches long and 4 inches wide. Neither the reproduction nor the original have been remade in a long time (as far as I know.)This reproduction is in excellent condition. However, there are some superficial gloss-level scratches on one side.It does not come with instructions, and I was never able to open it! However, it does not look warped or damaged at all.In addition, that means it is essentially like new!
