With this thinktea bottle, you'll be able to enjoy the benefits of a hot cup of tea wherever you go! Made of stainless steel and BPA-free, it is equipped with an airtight silicone lid and a tea infuser. You can warm up the insulated bottle with hot water for about 5 minutes to keep liquids hot for longer periods of time or cool it with ice-cold water for the same amount of time to create the opposite effect. Its convenient 16 oz format will allow you to sip away all day long! We recommend handwashing the product for better durability.
