Deceptively complex and surprisingly heavy, this pool ball-sized puzzle makes a terrific addition to your desk. It's crafted from three identical pieces of die-cast stainless steel, with satin-finished exteriors and pebbled interiors. Lined up precisely along six points, the three pieces slide effortlessly together to form a sphere, and once together, slide open and closed like a lens' aperture blades. Now available in a carbon black that's exclusive to Uncrate, it has a subtle patina that will be unique to each piece that will exaggerate over time.
