This is the same liner that comes with the Instant Pots and is stainless steel not the version with the non-stick coating. CamelCamelCamel has this hovering at $30-35 and the current price as the lowest recorded price.
My wife loves her instant pot and has been asking for a second liner so I jumped on this deal.
