In our latest competition, we've teamed up with Neubau to offer five readers the chance to win a pair of sunglasses that celebrate the centenary of the Bauhaus.
This competition is now closed. Congratulations to the winners, who are Lee Lawrence from Rochdale, UK, Pooja Kandala from Secunderabad, India, David Kupp from Ontario, Canada, Bren George from Ohaupo, New Zealand and Stefanie Hödlmoser from Graz, Austria.
The designs commemorate two leading figures of the Bauhaus, the influential 20th-century design school that was established in 1919 in Weimar, Germany.
Named Walter & Wassily, the collection by Neubau pays homage to Walter Gropius, the school's founder, and Wassily Kandinsky, a prolific painter and teacher at the Bauhaus.
We're giving readers the chance to win one of three colourways: white frame with black details, black frame with silver details, or black frame with matte brass details.
Neubau made the structure of the sunglasses a feature and also alluded to the use of steel tubes in Bauhaus furniture in the design.
"Neubau has harnessed the framework of Walter Gropius' movement to create an everyday object that encompasses high-end design and functionality," said the brand.
"This brings the Bauhaus 'form follows function' ethos to life."
A continuous line detail runs across the front of each lens, connecting to the arms at hinges near the temples.
A top portion of the lens rim on which this sits is covered with a corrugated continuation of the 3D-printed plastic used for the frame.
The lenses themselves are tinted and reflective, with the round shape nodding to the recurring use of circles in graphic prints of the era, according to the brand. Nose pads replace the need for a supportive bridge.
The Walter & Wassily collection was also designed to be ecologically conscious, from the product itself to its packaging.
"3D-printing the frames means they have no waste, unlike many mass-produced products which are cut out of large sheets of plastic or milling from acetate," Neubau told Dezeen.
Polyamide powder is used as the base component of the plastic frames, chosen for its strength, and lighter weight compared to acetate, as well as the fact that it is resistant to solvents.
The sunglasses cases are made from a cellulose material manufactured without the use of harmful glues, and the cleaning cloth that accompanies the glasses is made from recycled plastic bottles.
Both elements are packaged together using zero-plastic components.
Founded in 2016, Neubau focuses on environmentally sustainable methods of production, whilst supporting local projects such as installing green building facades in its home city of Vienna.
The limited-edition collection is also available to buy online.
Competition closes Tuesday 27 August. Five winners will be selected at random and notified by email, and his or her name will be published at the top of this page.
