Nicely turning puzzle (ok, somethomes some sticky corners), which has the base functionality of a Jing's Pyraminx (pillowed Halpern-Meier-Pyramid) with the additional feature to perform 60 degree turns. This allows the puzzle to change shape and (as proved in the Twistypuzzles thread) jumble. Weight: 64g Size: edge length 8.5cm, height ~7.7cm*
