3x3 Mod rubiks cube

This is a mod I have put together for the rubik’s brand 3x3, which makes the cube considerably faster and smoother. I would not say that it makes the best cube ever, yet it makes a decent cube many times better. Materials: Rubik’s brand 3x3 220 grit or similar very fine sand paper A piece of cloth or something similar Note: DO NOT OVER SAND YOUR CUBE!!! it makes it very loose, and it could start locking up all time.
