Using your Frank Green Reusable Ceramic Bottle is a breeze. First, open the easy - to - use Flip Straw Lid. You can fill it with your favorite hot or cold drink. Thanks to the triple - wall vacuum insulation, it'll keep your drink at the right temperature for a long time. The ceramic lining ensures your drink tastes just as it should. When it comes to cleaning, you can use warm, soapy water and a bottle brush. Just make sure to dry it thoroughly to prevent any moisture build - up. Also, since it's a limited - edition item, handle it with care to keep it looking great. Don't put it in the dishwasher or use abrasive cleaners as they might damage the ceramic lining or the stainless - steel body.
