The thing I love most about Luxey is the ability to customize your cup to suit your needs. I appreciate having a hot drink lid for those days when I want to enjoy my Earl Grey or London Fog instead of a cold beverage. The stopper makes the perfect addition to the hot drink lid to prevent dribbles. If you are like me and tend to alternate between hot and cold drinks throughout the day, it is so easy to throw this lid into your bag so you can switch between hot and cold lids as needed. It truly is effortless and a far nicer experience than drinking from a plastic disposable coffee cup lid.
