For some reason I just love drinking out of metal cups. I love the way they feel against my lips and I love that they somehow make my beverage seem to feel colder as I drink it. I could all be in my head but I really like the way these cups feel in my hand. They are very light so I’d imagine that they are hollow to create the double wall. There could possibly be some insulation inside but there’s really no way to checked as they are seamlessly sealed as to keep any moisture out of the inner wall. They are very easy to wash but as with all stainless steel if you are handing any food while drinking from these you may get some fingerprints on the cup. They keep my drinks cold. I do fear they may eventually dent if not handled with care but so far so good.
