This is a Hydro Flask water bottle (black, 18oz/532ml) that I received as a gift around 2023. It's a tumbler type with a sealed drinking spout. I used it a couple of times, but haven't used it since, so I'm selling it after storing it at home. When shipping, I will put it in a box from a different water bottle and attach the shipping label directly to the box. Retail price: 4950 yen
