Fissler 6.0L Pressure Cooker 18-10 This is a used item. As you can see in the photos, there are signs of use on the surface and inside of the pot. It is approximately 23cm in diameter and 16cm high (inner dimensions). It can be used as a pressure cooker, but steam may escape if the steam release fitting on the handle is slightly misaligned. In that case, manual adjustment of the fitting is required. When pressure is applied, the center of the lid will rise as shown in photo 10. Please understand that this is a used item before purchasing.
