Description

Interlock 4 is a handcrafted wooden cube brain teaser designed by Stewart Coffin. Four uniquely shaped pieces reassemble into a perfect 3x3x3 cube. The catch: the pieces do not just fit. They interlock in a specific sequence, so order and orientation matter as much as shape.

Handcrafted by Creative Crafthouse with Stewart Coffin's permission. Precision-cut pieces with natural contrasting wood tones.

4 wooden pieces.
Forms a clean 3x3x3 cube when solved.
Sequential interlocking mechanism. Order, orientation, and spatial reasoning all matter.
Engrave up to 45 characters at checkout.
