This 10 oz stackable mug is loaded with top-to-bottom insulation to keep your coffee hot from the first pour to the last sip. When the lid is removed, the built-in grooves on the bottom help multiple mugs stack perfectly on top of one another for easy storage. They are also dishwasher safe.
Please note: The smooth-sliding magnet component is not leakproof and will not prevent spills. Do not place mug over external heat source or open flame. Vacuum seal or other damage may occur.
