As soon as children get their first little teeth, they love to use them! That is why the NUK Kiddy Cup has a spout made of a resilient synthetic material (polypropylene). It can withstand little teeth and is particularly durable. 

It is very simple to remove the spill-proof and easy-functioning vent from the top, for easy and thorough cleaning. With a flexible connection to the top the cap is guaranteed not to get lost.
