Xv is a flexible shelving system that can be expanded horizontally as well as vertically. Assembly consists of 2 boards interlocking to create an "X" configuration. X's can then be stacked or further interlocked to become shelving units of varying sizes. "X", "V" and "T" clips are provided for support of corners. Boards can easily be taken apart and stacked away when not in use, saving valuable space. Great for wines, CDs, books and magazines.
