At Red Cup Living, our products are made from a strong, durable, reusable, and eco-conscious ABS plastic material, so you can feel good using this type of plastic. Our cup lid is designed to be used again and again. It helps keep your drink warm or cool and prevents any dirt from invading your cup. This lid suits 18 oz cups and is the perfect way to enjoy your coffee, tea, cocoa, or even water, soda, milk, or juice both on the go and lounging around at home. You can even enjoy sipping party drinks such as wine, beer, or cider with these lids. This sturdy plastic lid has a sliding closure to help reduce spills and an extended tab to help you easily take the lid on and off your cup. It's ideal for traveling in the car to work or school and will help prevent unwanted coffee spills in the office.
