Taking Care of Your Products

After a week of using your Flex Straw Cap for your daily water intake, it’s time for a refresh! We recommend cleaning this cap regularly to ensure all residue is removed and your product is ready for the next use. Please note that the Flex Straw Cap is not designed for use with hot liquids.
