The mug is also guaranteed to insulate whatever drink is placed inside because of its twin walls design. In addition to that, it is a spill proof mug, because of its spill proof grip pad, designed to reduce spillage, and it is designed in such a way as to prevent tipping over as well, and will detach itself quickly if lifted up straight.
