This is a tumbler from FedEx, the world's largest logistics company, founded in the United States and currently providing logistics services in 220 countries and territories worldwide. The tumbler is made of plastic with a double-layer structure, so it seems to have good heat retention properties. A rubber band is wrapped around the part of the tumbler you hold, making it non-slip and safe to use even with hot drinks! Size: Φ96/H180mm Material: Plastic
