Can you ID these storage bins? 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?

According to Liam Nilsen from The LEGO Idea Studio, he believes the storage bins may have been produced in-house by LEGO and are not commercially available. 



The online portfolio for GXN (the designers of the studio) mentions:


  Bespoke elements are accompanied by Open Desk furniture pieces, all
  fabricated by local makers and assembled on site.


I couldn't find the drawers on the Open Desk furniture site but it seems the parts containers are designed to fit snugly into the drawers.
