A perfect fit- the three sizes are super stretchy and perfect for daily tasks. Small is perfect for half an onion, that leftover avocado, and every cut fruit and veggie in between. Medium is optimized for sandwiches and individual bowls, while the large size is ideal for covering plates of food in the fridge and microwave. See more, save more- the translucent wraps allow you to see the contents inside and help you remember what you stored to reduce food waste. The best materials- made from patent-pending super stretchy and crystal clear silicone that is freezer safe, dishwasher safe, microwave safe, oven safe, and Bpa-free.
