Food Huggers are a set of four patent-pending reusable silicone covers that help preserve the freshness of leftover fruits and vegetables, and even the unused portions of cans and jars. Just push the leftover half down into the closest sized hugger and save it in the fridge until you need it again. When the food is pushed into the Food Hugger, the Food Hugger folds tightly (hugs) around the food and creates a seal to hold in the natural juices and prevent exposure to circulating air, which can cause food to spoil or dehydrate. Crafted from 100% FDA silicone, Food Huggers are 100% BPA and phthalate free. Food Huggers are also dishwasher, microwave and freezer safe. If you love your food, give it a hug. Set includes 4 green food huggers measuring 1-3/4, 2-1/4, 2-1/2 and 3 inches.
