Using your Corkcicle Cold Cup is a breeze. Just fill it with your favorite cold or hot beverage, insert the ceramic-coated straw, and you're ready to go. When drinking, the silicone straw tab allows you to adjust the angle for maximum comfort. For cleaning, it's best to hand wash the cup with mild soap and warm water. Avoid using abrasive cleaners as they can damage the ceramic coating on the straw and the finish of the cup. Don't put the cup in the dishwasher as high temperatures can affect the insulation. Store the cup in a cool, dry place when not in use. With proper care, your Corkcicle Cold Cup will serve you well for a long time.
