The THERMOS Shuttle Chef, with a capacity of 4.3L, is a thermal cooker that allows you to cook with residual heat after removing it from the heat source. I purchased it, but I got the wrong size, so I haven't used it. It's been a year. It's new since it hasn't been used. It's not an electrical appliance, so I don't think it's broken. Also, please refrain from price negotiations. - Brand: THERMOS - Model Name: Shuttle Chef - Capacity: 4.3L - Servings: 4-6 people Thank you for viewing.
