The Nils Camp NCC06 thermal mug features both simple structure and original design! The NCC06 is a thermal mug made of the stainless steel with a double wall, due to which it keeps the temperature of hot drinks for 12 hours and cold drinks for 24 hours. The NCC06 thermal mug offers an innovative opening system. To drink you have to press and hold the button - then the hole lock releases. On the other hand, to lock the opening, just release the button. The mug also has embossing in the grip area, making it easier to hold it and safer to move around. Another great feature is that the bottom of the mug has a non-slip rubber, which increases safety against spilling hot coffee or tea while the mug is open!
