Disposable cups feature a wax-coated interior to hold liquids for longer and prevent them from soaking through. Smooth rolled rim adds rigidity to the cup and ensures a leak-resistant lid fit. Disposable cups are made with a high percentage of renewable resources to reduce the impact on natural resources. Cold cups are designed for use with Solo LC12B10099, L12BLN0100 and LDN12C0090 lids (sold separately).
