Dark brown stainless steel thermos pot, made by THERMOS, with excellent heat retention. I used it for about 2 years to bring hot water when I was in charge of making tea for my child's sports team. I didn't use it very often. There are some scratches on the surface. I have carefully cleaned it at home. Capacity: 1.5L Model: THV1500(CBW) I think the heat retention is good. Please purchase with the understanding that this is a used item. I will pack it using recycled packing materials. Thank you for looking.
