Anti-Colic Glass Baby Bottle
Borosilicate glass with a natural rubber nipple, but a polypropylene screw ring, valve, and cap put plastic in the milk path.
Plastic-free verdict: Minimal plastic contact
Like the HEVEA, the nipple is 100% natural rubber (with rubber sealing parts too), which is a genuinely great zero-silicone soft component. The catch is the anti-colic system: the double valve is polypropylene, and the screw ring and travel cap are polypropylene as well. Because the valve and ring sit in the milk path, plastic touches the drink - so this lands at minimal-contact despite the natural rubber nipple and glass body.

Pros
- 100% natural rubber nipple and seals - excellent for zero-silicone parents
- Borosilicate glass body from France; premium hand-made rubber nipple
- Good choice for those specifically avoiding silicone in the soft parts
Cons
- Anti-colic valve is polypropylene and sits in the milk path
- Screw ring and cap are polypropylene too
- Natural rubber needs frequent replacement and hand-washing; latex-allergy risk
- Premium price; not fully plastic-free as sold
Notes

- Screw-ring material is our best reading (standard PP thread ring); valve and cap are manufacturer-confirmed PP
