Food Grade PET Material Containers: This food container set is made of food grade PET material, BPA-free, creating a safe and healthy eating environment for you. Its advantages are durability, health and hygiene, no odor, corrosion resistance and easy to clean. Can be used normally in the refrigerator. Orbital sliding storage container design: The orbital pull-out storage design does not take up extra space and can be hung on the side of the cabinet board or cabinet door - saving space while being more convenient and beautiful. Transparent box makes it easy to see the remaining items. Versatility: Food containers can be used for refrigerator organization. Each food storage container with lid has a super-strong rubber sealing ring that easily blocks air entry and provides significant leak-proofing. It can also be used as a refrigerator storage bin, meal prep reusable container, cereal container, flour sugar storage container. Not only can it be used to store snacks in the kitchen and living room; or to store coffee and sugar in the office. Total 12-Cup Extra Large Capacity: Each container has a capacity of 3.8 cups, and the three containers have a total of nearly 12 extra-large cups. The cup's wide mouth design makes pouring from the cereal container more convenient when in use. Cabinets with taller boards often waste a lot of space, and using food containers can make the most of that space. Christmas Gift: Are you as worried about it falling off as I am? We've tested it with a full load (full of water) and it still hangs securely under the cabinet board. The edge of the cup body moves along the sliding guide groove, making the integrated cup body and cup rim more stable. Listing: 1*Food Storage Container
