A fridge organizer is a storage container, often made of clear, food-safe plastic, that you place inside your refrigerator to maximize space, improve accessibility, and extend the life of your food. These tools come in various types, including bins, baskets, and drawers, and are designed to hold items like produce, drinks, and snacks. Key features include stackable designs for vertical storage, built-in handles for easy access, and some models offer drain plates to keep produce fresh by draining moisture.
