We build each 5 oz bottle from thermal-resistant borosilicate glass without BPA, BPS, or phthalates. The clear glass withstands rapid temperature changes during routine warming, boiling, and machine cleaning without clouding.
The soft silicone nipple flexes to match the natural rhythm of early nursing sessions. Built-in vents route air into the base of the bottle to maintain a continuous, steady milk flow without nipple collapse.
Each wide-neck unit consists of four basic parts that come apart in seconds. The open neck allows easy brush access, while every component can be sterilized in boiling water, bottle warmers, or microwave units.
Two solid white storage caps come in the pack alongside the standard collars and lids. You can swap out the feeding nipples to seal freshly pumped milk directly in the glass vessels.
