With the 16027 drink holder, König & Meyer is launching a product whose body is made entirely of bio-based plastic. These plastics contain a more than 50% up to 100% share of renewable plant-based raw materials. The use of renewable raw materials helps to conserve limited oil reserves and reduce harmful CO2 emissions. More information on bio-based plastics at: bioplastic.k-m.de. The 16027 drink holder made of bio-based plastic for glasses, cups and mugs is just as up to daily use as a holder made of conventional plastic. The metal clamp fits all standard stands with a tube diameter of 11 to 30 mm.
