The cup features a new soft silicone straw which is gentle to child’s tender gums and emerging teeth. The soft silicone straw is covered by an easy-to-use flip top cap. This uniquely designed feature protects the straw from contamination when not in use. Great for travel and short trips! The flip cap keeps the straw sanitary and clean. When ready to use the cup, simply flip the cap and sip from the No-Spill™ straw. Liquids pass through straw only when your child sips. The Leak Resistant Cup dispenses a variety of liquids, ranging in consistency from fruit juices, to milk and water.
