Important: the frame is cast in one piece. Complicated assembling is omitted and there is no slipping apart when moving the drawer tower times. The drawers are made of a plastic material that is not brittle (I have a very similar tower already in use for years) and they have an anti-tilt mechanism that can be overcome through lateral compression of the charge. This is handy and can not happen accidentally. I have it. My writing space for additional storage The drawers can be labeled great front with a label printer. The effective internal width of the drawer is 23 cm, a plastic flat file just fits into it. Unfortunately, loose-leaf binder of cardboard or Eckspannermappen and folders do not fit purely or slant. Otherwise, my full recommendation.
