The Flat N Stack lids form a virtually airtight and liquid-tight seal making them perfect for school lunches or for taking to lunches to work. When finished with them, just flatten them down to their 3cm thickness with the lid on. They are stored with the lid on so you never have top look around for the right lid. The Flat N Stack even has its own handles on the side making it easy to carry even if the contents are hot.

They are perfect for use in cupboards, refrigerator, freezer and they are dish washer safe, however we don recommend using the Flat N Stack in the microwave.
