Rubbermaid Brilliance Food Storage Containers make for a convenient solution for leftovers. They're available in a set of 6 pieces. Each one is made of BPA-free plastic for extra safety. They also feature latches to hold their lids on securely and help prevent spills. With 360-degree crystal clarity, the bases allow for easy viewing of food inside. These allow air to escape, allowing them to be microwaved without removing the lid. Thanks to a modular design, the containers can easily stack on one another to fit efficiently in the fridge. Use them to keep food fresh for later or to transport dishes to a party or picnic.
