The V-Cube ups the ante with their 4 x 4 x 4 Straight Cube. The patented V-Cube technology really comes in to its own on these elaborate cube constructions. Incredibly smooth rotations make for a clean, fast action – perfect for competition or improving on personal bests. With 7.40*1045 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 of whichare visible) and a solid cross for supporting their independent rotation on based axis. Brief instructions included, but get ready to be confused!
