Furniture Design Nucleus Modular Wine Rack by Thijs Goossink Nucleus consists of flat elements of extruded aluminium. Each element is identical in shape, has a scratch-proof satin finish and is anodized in blank or color. Low-tolerance-fit modular features make the rack infinitely expandable by adding elements in a sliding motion. Combination options are endless and Nucleus is easy to restyle at any time. Expand it along with your wine collection or match the dimensions of a limited space. Wall-mounted, free-standing, artful or subtle, the choice is yours
