Stainless Steel Food Storage Container 16 cm diameter 6 cups = 1.5 L These round airtight food storage containers are amazing! Available in 3 different sizes, they will fill your every need. The smallest container is great for baby food, toddler snacks or whatever else you can think of. Once you try these, you won't want anything else. They are made from #304 (18/10) food grade Stainless Steel, and the lid has a silicone seal. The containers are completely air tight. You can also write on the container with a non-permanent marker. This helps to specify the contents, date and owner. The bottom part of the container can be washed in the dishwasher, but the lid is not dishwasher or oven safe.
