This beautiful set of minimalist hanging lamps from Bünte & Remmler was designed in the 60s and is very rare. The design is beautiful and very simple making them a timeless piece.
The black shades have rust specles and the chrome on the top unfortunately has become dull. Other than that the lamps are in fairly good vintage condition. Especially when turned on the wear is not noticeable at all. 
Only sold as a set. 
There is only one other set available online and that is priced above 3000€.
