Here are the traditional 27
move Japanese Puzzle Boxes. Like all the work of Izumiya studios, They work well and have
a superior finish. Each puzzle box is stamped with the Izumiya hanko and comes
in a pressboard gift box along with opening instructions.
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
