This is a stainless steel pressure cooker. I purchased it over 10 years ago and have used it a few times. Therefore, there are some scratches and signs of use. Please refrain from purchasing if you are concerned. There is no outer box or instruction manual. You can download the instruction manual here: https://www.rakuten.ne.jp/gold/fissler/img/torisetsu/UM-PPPPCP.pdf The rubber gasket didn't seem to have deteriorated in my tests, but I think it would be safer to replace it. - Type: Pressure Cooker - Material: Stainless Steel - Handle Color: Black - Inner Diameter: Approximately 22cm - Brand Name: Fissler Thank you for looking.
