This insulated tumbler addresses that need directly with its 300ml capacity and double-walled construction, which is designed to keep hot drinks warm for up to 2 hours and cold drinks cool for up to 6 hours.

This design is leak-proof and can also grip a straw inserted through the opening, holding it securely in place to prevent spills. The materials used are confirmed as safe for both microwave and freezer use, adding to the cup's versatility.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eWith a 300ml capacity, this cup holds a typical serving size for a hot beverage like coffee or tea, or a refreshing cold drink.
