The NCB21 thermal cup from Nils Camp is characterized by both a simple construction and an original design! The NCB21 is a thermal cup made of stainless steel with a double wall, so it guarantees to keep hot drinks hot for 12 hours and cold drinks cold for 24 hours. The NCB21 thermal cup has a very convenient opening system. Simply pull up the opening handle and it's all done. Another great feature is that the bottom part of the cup has a non-slip rubber, which increases safety against spilling hot coffee or tea while the cup is open!
