The Coffee Stopper is a great stocking stuffer for the coffee and tea lovers from coffee shops! The Coffee Stopper™ replaces the splash sticks. I wanted to replace this problem with a reusable, eco-friendly solution. So, I created The Coffee Stopper, which is a patent-pending plug that plugs into HOT disposable (to-go) coffee cups (though, I have had customers use them for their reusable and cold drinks) to reduce splashing and keep the coffee/tea hot.
