Thermos Insulated Pot 2L This is the Thermos Stainless Steel Pot TTB-2000. It was used for hot water, so I don't think there are any smells or discoloration. It was used infrequently and for a short period, so it's almost unused. No instruction manual or box. Depending on the size of your hand, you can wash the inside of the pot by hand. How about it for your daily tea, coffee, black tea, or making baby formula? There are minor scratches on the exterior. Please refrain from purchasing if you are concerned about minor details as this is a used item.
