This tumbler uses a powerful 4,000 RPM motor to automatically stir your drinks, and fits perfectly in your vehicle's beverage holder. Constructed with translucent acrylic with a stainless steel inner liner that makes it thermal-insulated. Motor is activated with the press of a button on the tumbler base. Perfect for travel, office and home, with screw-on, slide open/closed lid and rubber coaster bottom. Tumbler is totally submersible but hand washing is recommended. Individually gift boxed.

NOTE: The use of ice in self-stirring mugs is not recommended!
