This is a 355ml black stainless steel tumbler with thermal insulation and cooling functions. It was included in a lucky bag, but I haven't used it and have kept it in its box, so I'd like to sell it. I took it out of the box once for the photos. Price negotiations are not accepted. Immediate purchase is welcome. - Brand: Starbucks - Color: Black - Capacity: 355ml - Material: Stainless steel - Features: Thermal insulation and cooling - Design: With logo Thank you for looking.
