Cirqula by Mepal has been designed specifically for a complete 'circle of use'. The food in these bowls can be stored in the freezer/fridge, heated in the microwave without the lid and can then be served directly to the table. Made of indestructible material and the transparent window in the lid allows you to see the contents clearly. The innovative, flexible lid is 100% airtight and leak proof. Practical and easy to store, can be stacked when they are filled and nestled together when empty.
