I've seen snapshots of official LEGO Group design studios in books published by DK and the like. They use neat, removable drawer inserts for sorting elements, but I haven't found them available anywhere online.
Does anyone know if these specific bins/drawer units can be purchased anywhere? Are they unique to the LEGO Group, or perhaps produced internally for internal use only?
