Stylish stainless steel tumblers with a curved design for easy grip. Purchased overseas several decades ago and stored unused. The storage condition is not good, and there are noticeable scratches and stains on the surface (please check the first photo). One of the two has a dented circular shape (please check the second photo). One has blue rust on the bottom of the cup (please check the third photo). The material may be tin, but it's not certain, so I've listed it as stainless steel. Please consider purchasing with the above points in mind. - Material: Stainless Steel - Type: Tumbler - Shape: Curved design - Base: Flat base with logo Thank you for looking.
