Tojo-bieg bookshelf. The German design team Eigenwert has created a smaller version of the popular Stell shelving system: the sturdy shelves made of white-coated MDF remain, but are now combined with delicate metal brackets as spacers within the shelf. The structural appeal of these metal angles, which are bent vertically at a 90° angle, gives the shelf its distinctive name. The eponymous German manufacturer offers the shelf in two angle heights, small with a shelf height of 23 cm and large with a shelf height of 31 cm. The shelving system is freestanding and can be extended in height with additional extension sets, allowing for flexible combinations of shelf heights – making it a perfect room divider. Tojo-bieg bookshelf base element. The shelving system includes 2 shelves, 3 metal angles, and feet for standing. Please feel free to expand this base with the optionally available extension elements to any desired height.
