SAVE TIME: make different smoothies in one shot. Use a separate blade for each smoothie, then wash them all at the end.
NO MORE LEAKS: high quality rubber gasket ensures the unit doesn't leak. Please be sure to push the rubber gasket snugly into the bottom blade before use.
HIGH QUALITY BPA-FREE MATERIALS: made from food-grade plastic and corrosion-resistant stainless steel.
