ChuChu PPSU Baby Bottle is made with super premium PPSU plastic which is the best and safest bottle plastic material.
This Japanese nursing bottle also features a one size silicone teat that fits all stages. The cross cut hole is opened by baby's suction and teething pressure, automatically adjusting the milk flow to the baby's need.
The air-valve in the silicone nipple prevents vacuum inside the bottle so the milk can flow continuously and babies can drink more actively.
ChuChu Baby feeding bottles are free of BPA, BPS, endocrine and any other disrupting chemicals.
