Know before you buy
Yes, the Mega Mug is designed with a tapered base diameter of 2.8 inches, which allows it to fit securely in most standard vehicle cup holders.
No, this mug is not dishwasher safe. We recommend hand washing the vessel and its components to maintain the integrity of the vacuum seal and the finish.
Thanks to its double-walled, copper-plated construction, this mug keeps drinks cold for over 24 hours and hot for over 9 hours.
No, the Mega Mug is made of stainless steel and is not microwave safe. Using it in a microwave can damage both the mug and your appliance.
The included lid features a secure fit with a removable slider for easy cleaning, but it is not designed to be 100% leak-proof if the mug is tipped over or placed in a bag.
The built-in silicone coaster base prevents the mug from sliding on smooth surfaces and helps protect your furniture from scratches or condensation rings.
