Again not a perfect design. .
So the previous bottle had the problem with the band of the top, got torn all the time, so it didn’t pop. I thought I try your new design… the sippy part has a whole which make NO sense . . if you are using the straw, you need a whole. Like this, you tilt the bottle and it leaks on that whole. Plus the sippy and the straw part is very small, like for babies or children. Not a fan either. Fire the person who accepts these designs without trying them well. .
