Press and drink, that is the principle. Press the drinking spout and the bottle opens, press again and it closes. Very handy during active moments and for a quick sip in between. Or just to take to school, of course! The bottle is guaranteed leak-proof and also easy for children to use. Thanks to the handy loop, you can take it with you everywhere without any trouble. The bottle can be put in the dishwasher as a whole, and the cap is easy to take apart.
