For best results, secure lid on cup then insert straw. Wash before initial use. Dishwasher-safe (top rack only) or wash in warm water using mild liquid soap. Rinse thoroughly. Do not boil. When dishwashing, place straw in a covered utensil basket. Cup may leak if shaken, squeezed or held upside down. Use with carbonated beverages or unfiltered juices is not recommended.
