Our Magma tumbler is made with stainless steel, double wall insulation, and a 22oz capacity making it versatile for both hot and cold beverages. The two lid options, one open and one closed, add to their functionality. The open lid is ideal for enjoying beer, wine, or cocktails, while the closed lid is perfect for keeping hot or cold drinks secure while you're on the go. Whether you're grabbing a coffee in the morning or enjoying a refreshing cocktail during a sunset cruise, these tumblers have got you covered. Their insulation will help keep your drinks cold for extended periods and your hot beverages warm for longer.
