I bought 144 cubes to make a Rubik's Cube Mosaic and these work great for that. I did have one cube fall apart on me (it somehow fit back together but it doesn't have a whole lot keeping it in place as it seemed a little deformed on the inside). I did buy these on sale so i paid less than a dollar for each individual cube. Most cubes are stiff when turning them and feel cheaply made (which was expected when buying this many cubes for this price). These cubes shipped within 3-5 business days which made me really happy (compared to buying them directly from China and waiting a month for the shipping). Overall I'm happy with my purchase and I may consider buying this again if I ever need to make another mosaic!
