The first thermos mug launched by S'well was selected as a recommended product in Oprah Winfrey's "O Magazine", which boosted S'well's sales and made it popular on social platforms, and Kaley Cuoco, who played Penny in the American drama "The Big Bang Theory", is a big fan of S'well. In its fourth year, S'well's sales revenue increased by 400% and surpassed $100 million in 2016.
 
The shape of the S'well thermos cup is similar to that of a bowling bottle, with a slender body and a diameter of 3.2cm, which is just enough to put in a standard size of ice cubes, but it is not convenient to clean with a small diameter and long cup. From the perspective of styling design, S'well's highlights are not as good as Corkcicle, its appearance is more from the color, paint and pattern of the cup, and the texture and pattern of the shell are made of soybean environmentally friendly pigments, which are non-toxic and harmless.
 
So far, S'well has launched more than 100 colors and patterns, the existing wood grain series, metal series, satin series and other fifteen series of thermos cups, wood grain series each cup is randomly colored, sports series cup lid on the handle design, easy to carry. However, the bottom of the S'well is prone to paint peeling, which can damage its appearance. S'well currently has no official sales channel in China, and it can be purchased through Haitao for about 220 yuan.
