This is a brand new Calvin’s Cuboid 3x3x5 X-Shaped Cube, co-designed by Aleh, Tony & Evgeniy. It is fully functional, meaning any slice or side can rotate freely. Its unique design makes it a very fun puzzle to play with.
This puzzle comes fully assembled and stickered from the factory. Note that lubricating and working in the cube improves its performance. It is highly suggested to lubricate the cube to make it move more easily.
