Overview
Coil Pocket Puzzle
Bars of brass and steel intertwine to form a small box. You may absentmindedly separate the two pieces after an hour or two of fiddling but good luck getting them back together again without great concentration. A handsome example of a classic two-piece disentanglement puzzle.
Designed by Ed Nagata for Hanayama of Japan.
