Using this Hydro Flask tumbler is easy. Just open the closeable press-in lid, fill it with your favorite hot or cold drink, and slide the lid shut. You can drink directly from it or use a reusable straw. For cleaning, you can simply put it in the dishwasher thanks to the Color Last powder coat. When it comes to storage, keep it in a dry place. Avoid using abrasive cleaners as they may damage the powder coat. Also, don't overfill the tumbler to prevent spills when closing the lid.
