The small piece of Ichimatsu yosegi featured on the lid makes for a wonderful
contrast to the box's otherwise uninterrupted wood exterior (see picture of rear of
box to right).
The puzzle mechanisms are very smooth and are of high quality. Opening
instructions and a high quality pressboard gift box are provided. At only $50 it makes a
great gift!
A mechanical puzzle is a self-contained object, composed
of one or more parts, which involves a problem for one person to solve by manipulation
using logic, reasoning, insight, luck, and/or dexterity. - Jerry Slocum
