Can you use the Mepal Mio sippy cup without the anti-leak valve?
We are often asked, "My child finds sucking through the valve too difficult. Can I use the cup without the valve?" The answer is very simple: yes, you can. The Mepal Mio leakproof sippy cup can also be used without the valve. However, the cup will no longer be leakproof and will leak when held upside down.
