Rubik's 3x3 Tactile Cube
Improving on the original Rubik's Cube is difficult, but here's an interesting addition: each color now has a unique texture, allowing you to differentiate colors based on how they feel. Besides being a nifty tactile enhancement, it also allows seasoned Rubik's aficionados to solve the puzzle with their eyes closed!
This 3x3x3 Rubik's Cube has been enhanced with embossed shapes! By adding shapes to the colored sides of the cube, the Rubik's Tactile Cube is now playable (and solvable!) with your eyes closed!
