We sell products from the famous German desk accessorie company Werkhaus. For the past 6 years Werkhaus has designed high quality products for the desk with MDF made from waste from the timber industri. The MDF does contain a binder which comes from non-renewable ressources, however the ammount is very little. In the series that we offer, you will find products made without the use of binder, these products are of a different quality, the surface is more rough and there are more spots in the material. However if you want the ecological most correct choose the eco-series.
