Aluminum Bialetti Moka Express, silver design, for easy coffee brewing. It was from 2004, not over 10 years ago, but even earlier. After purchasing it, I used it a few times and then put it away until now. The rubber gasket has deteriorated and is sticky. It is stuck to the funnel and the joint of the bottom part. (Photos 7-9) I just tried making espresso with it a moment ago, and a little espresso leaked from the joint between the top and bottom. (Photo 6) When purchasing, we recommend buying a new rubber gasket separately. Regarding the safety valve (pressure release valve), I couldn't find much information online. Please purchase if you are satisfied with the above condition. - Brand: Bialetti - Model Name: Moka Express - Material: Aluminum - Color: Silver - Handle Color: Black - Bottom Condition: Minor scratches - Outer box not included - Size: Base diameter 8.3cm x Height 16cm Thank you for looking.
