The primary-plastic edition of XJ's formidable TuttStarminx - natural translucent internals showing through every one of its thirty-two triangular faces - and strictly limited to just sixty-six pieces worldwide.

Mechanically identical to the black run: twenty turning hexagonal faces on a pentagon-locked frame, full jumbling capability, and the turning quality that made early owners forgive its brutal difficulty. The primary edition simply adds collectible scarcity to an already desirable puzzle.

Sixty-six exist. When they are gone, they are gone.

Features:

• Limited to 66 pieces worldwide
• Natural primary-coloured plastic
• Jumbling face-turning mechanism
• Collector-grade production quality
