Store cut onions in the Onion Saver® food container to keep onions fresh longer. Using the onion keeper will reduce food waste as your partially used produce will stay fresh longer and will be recognizable in a crowded refrigerator. Meanwhile, onion odors stay contained, keeping your fridge fresh and organized. For some fun when entertaining, use these as serving pieces for burger toppings, etc. Everyone will know where to find the sliced onion rings.
