Karat's high-quality enclosure lids are specifically designed for Karat 10-24oz Paper Hot Cups. These lids have a flap over the sipper hole, which can be closed to prevent leakage when walking or driving; all the while keeping your drinks warm for longer. Our curves are our trademark. The flap can also be secured down if you want to keep sipping without having to open it.
