This set includes 8 collapsible food storage containers, available in both rectangular and round shapes, with four sizes each: 11.8oz, 16.9oz, 27oz and 40.5oz. They come in four colors: yellow, green, blue and red, allowing for food classification by color. The various shapes and sizes can meet different food storage needs and keep food fresh, suitable for indoor scenarios such as kitchens, RVs and trailers as well as outdoor activities like travel, camping and picnics. Made of food-grade silicone, the containers are soft and unbreakable. The clever collapsible design saves up to 50% of space, fitting easily into kitchen and pantry compartments, cabinets or drawers. The containers have a temperature tolerance range from -4°F to 428°F (-20°C to 220°C), making them safe for use in microwaves, freezers and dishwashers. When heating in the microwave, the air vent valve on the lid must be opened or the lid removed entirely; they can be placed on the top rack of the dishwasher for cleaning. Each lid is equipped with four snap buckles and a high-quality silicone sealing ring, which creates an airtight seal to extend the freshness of stored food and protect it from contamination caused by high temperatures or insects. When attaching the lid, press only the side tabs instead of pressing down on the lid directly to prevent the container from collapsing and spilling its contents. Color: Multi-Color.
