NEVER BEEN USED. Super cute and perfect for the winter! Stainless steel. It keeps your drinks cold or hot depending on the beverage. The top, as you can see in the 5th and 6th photos, is a cup itself. You can pour some of your drink into the top and it’s a mini cup. Reason it was never used was because I have other stainless steel cup that I use all the time and this one ended up never being used, so I decided to put this one up for sale. If you have any questions, comment down!
