8oz Glass Baby Bottle Stage 2 Nipple, Stopper, Cap

The bottle body is named as thermal-shock-resistant borosilicate glass, an inert material with zero microplastic release, with the cap and ring specifically identified as polypropylene rather than an unspecified plastic.

The cap is BPA/BPS-free and phthalate-free, going beyond a bare BPA-free claim, but the brand's own claim only state BPA, phthalate, PVC, polycarbonate, lead and latex free without naming BPS or BPF for the finished nipple and cap together.

An independent consumer advocate ran XRF testing across multiple colors and sizes of this bottle line's factory parts and found them negative for lead, cadmium, arsenic and mercury, with results consistent across every color and size tested.

The borosilicate glass bottle, caps, and silicone parts are explicitly rated for boiling-water sterilization and freezer-to-boiling use, distinct from the brand's soda-lime hydration line which cannot be boiled or frozen; the brand does not claim microwave safety for its bottles.

The nipple is named as silicone, with a described venting system and its country of manufacture (France for the 4oz/9oz Stage 1 nipple) disclosed, but no medical- or food-grade designation, post-cure detail, or certification is published.

We queried the complete CPSC recall database (9,966 records, 1973-2026) directly for this brand and found no recall record in any role, at any date. The corpus's coverage of comparable product classes (pacifiers, toys, cribs) was confirmed with a control search, so the clean result reflects the brand's absence rather than a failed query.

No concrete replacement interval or visible degradation signal (cloudiness, stickiness, cracking) is published for the glass bottle or its silicone nipple; a third-party reviewer instead frames the glass body as lasting indefinitely, which sidesteps rather than answers the question.

The bottle is tested to meet FDA standards by independent testing laboratories, but no specific standard, lab name, or certificate number is given anywhere, and third-party roundups repeat 'FDA tested' without naming a test or report.

The glass and silicone nipple are made in France, the cap and sleeve in the U.S., with a stated 1-year warranty on glass baby bottles and a replacement-glass program for broken bottles when the sleeve and cap survive.
