This cube is a white plastic cube, it has strange caps on all of the pieces, the edge pieces look unlike any cube I've seen before, they are very small, almost semi-circle like, they don't go inward like other puzzles, the corner pieces are even harder to explain, I would have pictures but I am posting from an Iphone and I haven't figured out how to do that yet. All of these pieces as hollow. It pops almost every solve unless I have it on very tight tensions, and then it just becomes a hassle to solve because it locks up so much
