A single piece of cardboard is folded and fixed together to create this rectangular lamp by Berlin designer Johannes Kiessler.

Johannes Kiessler used one flat piece of cardboard to create the rectilinear body of the lampshade and it is held together with screws.

"At the beginning, Numerouno was just an experiment to understand if it is possible to market a semi-industrial product which is attractive, locally produced and yet affordable," said Kiessler.

The lamp is hung from two points using a single string, which can be adjusted to different heights.

Kiessler produces the designs in his studio and sells them on his website.

Here is some more information from the designer:

Numerouno is a new pendant lamp in cardboard designed and manufactured by Johannes Kiessler in Berlin. It can be mounted on your dining table, your kitchen counter, your working- or meeting desk or your workbench. It is quick and easy to install, uses one 21W T5 low energy tube and gives a beautiful, warm and pleasant light. Also, you can adjust its height for a more personalised setting.

At the beginning, NUMEROUNO was just an experiment: to understand if it is possible to market a semi-industrial product which is attractive, locally produced and yet affordable. Also, many of us have lost the awareness of where the things that surround us actually come from and how they are made. Therefore, in the tradition of Berlin's industrial past, Numerouno is manufactured and assembled in the central district of Charlottenburg, just a 2-minute walk away from Zoo-Station.
