Planet mugs from Starbucks are real.

Mug is a type of cup, which refers to a cup with a large handle. Because the English name of mug is mug, it is translated as mug. Mug is a type of household cup, generally used for hot drinks such as milk, coffee, and tea. Some Western countries also have the habit of drinking soup from mugs during work breaks. The cup body is generally a standard cylindrical or quasi-cylindrical shape, and has a handle on one side of the cup body. The handle of a mug is usually in the shape of a half ring and is usually made of pure porcelain, glazed porcelain, glass, stainless steel or plastic. There are also a few mugs made of natural stone, which are generally more expensive.
