This series of vacuum bottles is designed to meet the drinking needs of Chinese consumers in different scenarios. The bumpy texture makes it easier for users to grip, and the user does not feel too cold due to their hand clinging to the stainless steel cup. For the desktop mug with silicon lid, the designers chose use a non-stick coating to isolate the inner wall of the metal, making the tea and coffee more healthy and the taste better. The design concept is growth, and the overall shape of each product is taken from the different parts of a standard plastic water bottle.
