SERVING SIZE: You decide what size smoothie to make, not us. No pre-set portions. STORAGE: Our bags fit 3 times as many smoothies compared to smoothie cups. FOOD WASTE: No furry blueberries, slimy spinach, or squishy strawberries ever again. SUSTAINABILITY: We are NOT single serve. Our large bags make 6-12 smoothies. You are helping save our planet. UP CYCLE: Never use a zip lock again. Reuse the bags for food storage, marinating foods, school supplies and more.
