The Meffert's 12 color Pyraminx Crystal V2 (White) is a stunning and improved puzzle that combines two different puzzles into one. A Megaminx with an exterior layer that forms the Pyraminx Crystal is concealed within. This is an advanced puzzle that requires careful handling, particularly during the break-in phase. To properly align the pieces, gently tap one of the Crystal's twelve sides on a level surface. You may do this at any point while solving the puzzle.
