Know before you buy
Yes, the mug features a tapered design with a 2.8-inch base diameter, which is engineered to fit most standard vehicle cup holders despite its large 40oz capacity.
No, this tumbler is not dishwasher safe. We recommend hand washing it to preserve the integrity of the vacuum seal and the vibrant exterior print.
The mug features a permanent silicone base that acts as a built-in coaster. This prevents the mug from sliding on smooth surfaces and protects your tables from scratches or condensation rings.
The included X-Large Straw Lid is designed for convenience and ease of sipping, but it is not 100% leak-proof. It is best to keep the mug upright during transport to prevent spills.
Absolutely. The double-walled, copper-plated vacuum insulation is highly effective for both extremes, keeping drinks cold for over 24 hours or hot for more than 9 hours.
The mug features a high-quality print on a glitter background. While it is durable for everyday use, we recommend avoiding abrasive scrubbers during cleaning to keep the design looking crisp.
