The Safe Sippy2 bottle is the world's first 2-in-1 sippy-to-straw drink cup for kids. The next generation Safe Sippy has these great new added features: - No-spill sippy valve and a straw and adapter that instantly converts the cup from sippy to straw bottle. It is the only 2-in-1 cup on the market - Travel cap for keeping the spout clean - Travel plug to ensure no leaks when the cup is being carried in a purse or diaper bag - In addition, The Safe Sippy2 sports all of the well-known features of the original Safe Sippy cup: - 11 ounce volume - 304 food-grade stainless steel vessel - BPA and phthalate free - Colorful protective TPR sleeve that provides insulation against cold liquids and acts as a cushion to protect the cup (and furniture) from denting and banging - Straw shaped spout, because research has shown that the straw design is better for physical and speech development of kids - Removable handles - Dishwasher safe
