Eco-friendly hot cups are made from renewable resources to reduce your environmental impact. Disposable material makes cleanup fast and simple after each use. Smooth rolled rim enhances the cup's strength and ensures a secure lid fit. Paper cups can be used with compatible Genuine Joe lids (sold separately). They are lined with PLA (poly-lactic acid), a renewable resource, which is compostable. These cups are ASTM D6868-11 compliant and BPI certified.
