Cup sleeves are protective coverings designed to insulate hot beverages, making them easier to hold. They are commonly used in coffee shops and cafes to prevent burns from hot cups. Made from materials like cardboard or foam, cup sleeves provide a barrier between the drinker's hand and the hot surface of the cup. In addition to their practical use, cup sleeves often feature branding or promotional messages from businesses. This allows companies to enhance their visibility while providing a functional item for customers. Many establishments also offer reusable cup sleeves as an eco-friendly alternative to disposable options, promoting sustainability in the beverage industry.
