Wow.......I guess that cube is at least more than 1 year old already right???

I bought mine for half year already, and the stickers have started to peel off........I guess going to be the same as yours soon......

You can buy replacement stickers if you want........

But there's a type that doesn't use stickers, they paint on the cube itself instead........
In that way, the colour won't be peeled off........

But I'm not sure about the lifespan of the paint........

By the way, the cube itself is smoother than the 1 I bought from Toys R Us........
