The DaYan TengYun 2x2 is the first 2x2 in the TengYun range of puzzles. It features medium/strong magnets and is not currently available in stickerless. A unique feature to the DaYan TengYun 2x2 is the wavey ridges on the edges of the pieces, this design helps aid smoothness and also helps to spread the lube around the cube.
