This flour container set is made of BPA free and durable plastic, which has a longer service life than many other plastic containers. The clear containers make it convenient to see the contents inside, allowing users to easily get what they need without opening each container. These sealed and stackable boxes are designed to save space, enabling efficient organization of the food pantry and maximum use of space. They can easily fit into refrigerators, freezers or cabinets, making the food storage area more organized and free from clutter. The food storage containers are suitable for storing a variety of baking supplies, such as bread, flour and brown sugar. They are also suitable for dry foods and bulk foods, including pasta, oats, rice, grains, nuts, corn, chips, snacks, coffee, tea and legumes. These large food storage containers are designed to be leak-proof and airtight, which helps keep food fresh. The secure side-lock lids with blue silicone gaskets ensure a tight seal, protecting food from air and water while preventing liquid foods from spilling. The 10-pack flour and sugar containers come in 3 different sizes, including 2 extra large containers (6.5 L/5.9 qt.), 2 large containers (5.2 L/4.7 qt.) and 6 medium containers (2.5 L/2.3 qt.), along with 4 measuring cups and 24 labels. The large capacity makes them suitable for storing flour, sugar or other bulk foods. Color: Black.
