Römertopf oval bread pot Medi for keeping and storing bread and rolls fresh for many days. Multiple test victories confirm: There is no better material for bread than natural clay. The special breathable clay acts like a natural air conditioner with its sophisticated ventilation holes (2x3) to ensure the necessary air circulation. The unglazed underside of the lid absorbs excess moisture. The bottom part is glazed on the inside, making it easy to clean and dishwasher safe.
