I've used this for about six months and then left it on a shelf for a while, so there's some slight water stains and rust. However, the inside is relatively clean. It's a bit old, so it's 6.0L, but I've set the price low. This is a stainless steel T-fal pressure cooker with a safety valve, so it's safe to use. - Brand: T-faL - Type: Pressure Cooker - Material: Stainless Steel - Color: Silver - Features: With safety valve Thank you for looking.
