The V-Cube ups the ante with their 4 x 4 x 4 Pillow Cub. The patented V-Cube technology really comes in to its own on these elaborate cube constructions. Rounded edges and corners make an ergonomic skill toy that meets the needs of the most demanding speed-cuber. Incredibly smooth rotations make for a clean, fast action - perfect for competition or improving on personal bests. With 7.40*10^45 possible permutations and weighing in at just 157g the V-Cube 4 x 4 x 4 is an excellent example of engineering and product development. The cube consists of 98 smaller 'cubies', (56 are visible) and a solid cross for supporting their independent rotation on based axis. Brief instructions included, but get ready to be confused!
