The puzzle is to remove the nails from their stand then separate the two nails.
The nails are gold plated and the wooden base is made from Rose Alder with a groove cut to stand your business cards or notes in.
A popular form of the original nail puzzle was patented in 1910 in the USA by Walter Jenkins, however it was certainly know much earlier. In fact, it was probably being played with as early as the first half of the 17th century.
Look for the extra bend Mr. Puzzle has added to increase the difficulty of the puzzle.Size 160mm x 40mm x 65mm (to top of nails as they sit in the stand)
