316 Stainless Steel Thermos Flask, Vacuum Insulated Bottle, with Drinking Cup, Leak-proof, Suitable for Coffee, Tea, Gifts, Outdoor Use - White

This cup features a 316 medical-grade stainless steel inner liner. Made of food-grade material, it's safe, odorless, corrosion-resistant, and doesn't easily breed bacteria, ensuring peace of mind with every sip. It also boasts double-layer vacuum insulation technology, creating a vacuum layer between the inner and outer shell to block heat conduction and convection, achieving a double benefit of 24-hour heat retention and 12-hour cold retention—hot coffee brewed in the morning remains fragrant and piping hot by evening; chilled lemonade poured in on a summer day remains refreshingly cool in the afternoon, meeting all your needs in one touch.
