We've taken into consideration both your baby's mouth and the breastfeeding mechanism. Four-stage flow adjustment function that can accommodate each baby's pace. The top and bottom of the mouth are shaped differently. After much dedication, we've come up with an asymmetrical shape. Three nipple openings that make it easy for saliva to mix with the milk [swallowing function]. [Product size] W65 x D63 x H214 [Country of manufacture] Japan, bottle only made in Germany
