The Beysis Re-usable Coffee Cup is as functional as it is sleek. Made of high quality, double-walled stainless steel, it keeps coffee hot for 12 hours and iced tea cold for 24. Forget about unreliable and difficult to clean spring-loaded openings and flip-top lids - we’ve designed a silicone sealed, screw top lid so robust the cup can be thrown in a bag without the risk of leaks or spills. We’ve spent hours perfecting the ergonomic lip and made the dimensions a perfect fit for most car cup-holders. It’s these small details that set our cup from others on the market. - Capacity: 11.5oz (340ml) - Dimensions: 2.75" diameter by 5.7" height (7cm diameter by 14.5cm height) - Double walled stainless-steel - Vacuum insulated - Keeps liquids hot for 12 hours and cold for 24 - BPA free
