Unlike a pressure cooker, you can open the lid while simmering, and the glass lid allows you to see the contents. Small fish bones become soft, and simmering is quick and convenient. This is a gift and has been stored at home. There is no outer box. Compatible with IH. Size: 30CM, 5.5L. The outside of the pot is still very beautiful. I cannot lower the price any further due to high fees. Returns are not accepted, so please understand.
