Jet delivers intense, mind blowing flavor. We like to call our smoothies "fresh fruit with a straw." Or how about flavored iced teas and lemonades? With Jet's flavor, the possibilities are limitless. A 16oz serving contains half pound of real fruit, as well as Vitamin C, and antioxidant-rich green tea.� Jet Teas have a six month shelf life. No refrigeration is required until opened, and they stay good in refrigerator up to four weeks after opening. Just add ice and blend.
