A mug is a type of cup, a drinking vessel usually intended for hot drinks such as coffee, hot chocolate, or tea. Mugs have handles and usually hold a larger amount of fluid than other types of cups such as teacups or coffee cups. Typically, a mug holds approximately 250–350 ml (8–12 US fl oz) of liquid. A mug-shaped vessel much larger than this tends to be called a tankard.
Mugs typically have a straight-line profile, either perpendicular or flaring. However, this is not defining for the form, and a curving profile is possible. A single vertical handle is essential (otherwise the vessel is a beaker), as is the lack of a matching saucer. A mug is a less formal style of drink container and is not usually used in formal place settings, where a teacup or coffee cup is preferred. Shaving mugs are used to assist in wet shaving.
