Mary Square Tumbler

Thanks to the triple-walled vacuum insulation and copper lining, this tumbler is designed to keep beverages hot for up to 12 hours and cold for up to 24 hours.

The flip-sip lid is specifically engineered to be leakproof, making it safe for travel. However, we always recommend keeping the tumbler upright in your bag to prevent any accidental pressure release.

While the 40oz capacity offers great hydration, the base size can vary by vehicle. We recommend checking your car's cup holder dimensions, as this larger size may be a tight fit in some standard consoles.

The anti-slip silicone base provides extra stability on smooth surfaces like desks or countertops, preventing the tumbler from sliding around or tipping over easily.

The matte finish is designed for durability and a modern look. While it is resistant to everyday wear, like any matte surface, it may show light scuffs over time if handled roughly.

To preserve the integrity of the vacuum seal and the matte finish, we recommend hand washing this tumbler with warm, soapy water rather than putting it in the dishwasher.
