Stop settling for lukewarm drinks. Our Stainless Steel Flower Design Tumbler is built with double-wall vacuum insulation that creates an airless space between two walls of stainless steel. This virtually eliminates temperature change, allowing your hot coffee to stay steaming throughout your morning meetings and your iced water to stay freezing during a long afternoon commute. It is the year-round hydration solution that performs as beautifully as it looks, regardless of the weather outside.
