Elegant for a cocktail, sturdy for outdoor use. The 350ml thermal mug is made of double-walled, vacuum-insulated stainless steel to keep your morning coffee or happy hour drink at just the right temperature. Plus, it's equipped with a tri-mode lid for flow control, so you can drink fast or slow as you please. The durable powder coating is scratch-resistant and allows you to clean the mug in the dishwasher. Thanks to its non-slip silicone base, you won't have to worry about the cup falling over and breaking. Free from BPA, BPS and BPF.
