An interesting non-twisty puzzle from QiYi. The XiangYun 4 piece puzzle features 4 pieces of clear acrylic cut into unique shapes. The idea of this quirky puzzle is to fill the base with the 4 acrylic shapes (easier said than done).
Note: The pieces of acrylic have a protecting layer that can be peeled off from both sides.
