The most functional drinking accessory on the planet. The 3-in-1 design combines hundreds of dollars of products into one awesome, must-have gadget. Use it for 16 ounce cans, 12 ounce cans, and fits 16 ounces of fluid so you can also use it as a tumber for hot or cold beverages, with the included lid! Loading it is simple. Simply push the can inside and the airlock technology will hold it in place. When you’re done, unscrew the gasket and pull the can out to load your next beverage! It is triple insulated, which is what separates it from everything else, and prevent condensation. It insulates your hands from the cold and keeps your favorite beverage ice cold, or warm, until the last drop!
