Know before you buy
Yes. The Mega Mug is specifically designed with a tapered base that measures 2.8 inches in diameter, allowing it to fit securely in most standard vehicle cup holders.
Thanks to its triple insulation technology, this mug keeps beverages cold for over 24 hours or hot for more than 9 hours.
The included straw features a soft, flexible silicone tip that is easy to clean. While the mug itself is durable, we recommend hand washing to maintain the integrity of the vacuum seal and finish over time.
No, the double-walled, vacuum-sealed construction ensures the exterior remains condensation-free, so you won't need a coaster.
The silicone base is integrated to provide a slip-free, scratch-free, and noise-free experience on hard surfaces. It is designed to stay in place to protect both your mug and your furniture.
The lid is designed to be secure and fits tightly to prevent spills during normal use. However, it is not intended to be 100% leak-proof if the mug is tipped over completely or tossed into a bag.
