I purchased this item, but I never used it because my intended purpose for it changed. I've kept it in storage, unused. Since I don't anticipate needing it in the future, I'm putting it up for sale. This is a 1.6L stainless steel thermos, excellent for both heat and cold retention! The wide mouth makes it easy to add ice, making it very convenient!
