Tojo SOLO is a building block (w: 70 cm, h: 35 cm) from which different sizes of an individual shelf can be assembled as desired.‎ Without tools, solid structures are created in different heights and widths.‎ The elements are simply inserted horizontally and vertically, creating a stable unit.‎ The combination options of Tojo SOLO are determined by the number of blocks and are expandable if necessary.‎
