Doesn’t leak when hold up side down my son throwing it and it splashing which is normal few times he manage to throw it so strong it opened or maybe i didn’t closed it properly

These things are like magic water goes in lid goes on and then doesnt come out unless its being drunk from or the lid being peeled off

This sippy cup is the best i’ve ever purchased it leaks slightly when thrown which is understandable but if knocked over accidentally nothing comes out

The rubber pops on and off so you can get a really thorough clean

So will have to clean it meticulously

If you put them in a bag they will leak the second something else presses on the lid

If you drop on the floor same thing
