Exquisite craftsmanship and clever calculations combine to create two exceedingly difficult puzzle boxes perfect for fans of advanced mathematics. The Ternary Box requires eighteen moves to open and the Quinary Box requires fifty! Please don't ask us to explain the underlying mathematical principles.

Designed by the brilliant craftsman Hiroshi Iwahara, both Visible Drawer Puzzle Boxes are made from Walnut, Wenge, Padouk, Maple and acrylic "see-through" panels (hence the name "Visible"). Please note: the hidden storage compartment is considerably smaller than the exterior of the box. Made by hand in the Hakone mountains of Japan.
