USE: Wash cup and valve before first use and immediately after each use. Before first use, pinch valve at stem to activate. Push SipEase valve firmly into holes on inside of lid. Position valve so larger stem fits securely into sipping spout (point arrow on valve towards sipping spout). To clean in dishwasher, remove valve and spout and place in Valve Storage area in lid, place lid and cup in dishwasher top rack. Or hand wash separately in hot soapy water for one minute (rinse thoroughly). Avoid abrasive cleaners. Discard and replace valve if it shows excessive wear or residue build-up. Replace SipEase valves sold separately. Screw lid tightly to guarantee seal.
IMPORTANT: Never use with carbonated beverages or juices with pulp. Due to SipEase valve, some liquid will remain in cup.
CAUTION: Do not use with hot liquids, burning may result.
WARNING: To avoid injury, do not let child walk or run while carrying cup.
