The Joovy Dood Sippy Cups with Insulator are the best, most full-featured training cups on the market today. They are available in two sizes, a 7 ounce training cup and a 9 ounce drinking cup. The Dood 7 ounce Drinking Cup comes with a soft spout. The ergonomic shape of our Dood Soft Spout is specially designed to protect gums and pallet during teething. The soft spout provides an easier transition from bottle to cup and is recommended for children 6 months and older. The Dood Sippy Cups include the same one-piece CleanFlow vent system as our Boob Baby Bottles. The vent provides consistent venting regardless of how the cup is held. They also include non-spill valves to eliminate leaks, flexible handles that make them easy to hold, and caps to keep spouts clean. The included insulator keeps liquid at their desired temperature longer. It also allows you to freeze liquids inside the Dood Sippy Cup, extending thaw times while you travel. The Dood Insulator is easy to remove so you can use the Dood Sippy Cups with or without it. The Dood Sippy Cups are made of clear and colorful PP (polypropylene) and are BPA, PVC, phthalate and lead free. Available in purpleness and turquoise colors.
