Integrated Nipple–Collar
The nipple and collar are molded as a single silicone component, removing plastic parts, hidden crevices, and any risk of microplastic exposure.
Silicone Cap
Non-toxic protection, made simple. Crafted from 100% food-grade silicone — no plastic, no chemical leaching. Keeps the nipple clean and protected between uses.
Borosilicate Glass Body
Made from premium borosilicate glass — resistant to thermal shock, easy to sterilize, and inherently toxin-free for peace of mind.

FAQs
Yes. The bottle body is borosilicate glass. The nipple-collar and cap are food-grade silicone. There is no polypropylene threading, no plastic vents, and no hidden plastic components anywhere in the design.
Just two. The glass bottle and the integrated nipple-collar. The silicone cap protects the nipple between feedings but doesn't need washing unless visibly soiled.
Yes. The integrated nipple-collar is a single replaceable component. We offer slow, medium, and fast flow options. Simply swap out the entire nipple-collar as your baby's feeding needs change.
The bottle is premium borosilicate glass (the same material used in laboratory glassware). The nipple-collar and cap are 100% food-grade silicone, LFBG certified. No plastic. No coatings. No mystery materials.
Yes. The slow-flow nipple is designed for newborns (0+ months). The bottle is third-party lab tested and verified free from BPA, phthalates, microplastics, and other harmful chemicals.
Yes. The bottle is safe for boiling water, steam sterilizers, UV sterilizers, and dishwashers. Borosilicate glass is thermal-shock resistant and won't crack from temperature changes.
Borosilicate glass is more durable than regular glass, but it can break if dropped on hard surfaces. We recommend using a silicone sleeve (available separately) for extra protection during travel or when learning to hold bottles.
Our materials are third-party lab tested for BPA, BPS, phthalates, dioxins, and microplastics. We don't just claim toxin-free—we can prove it.
Most glass bottles still use plastic collars, threading, or vent systems. Ours is the first with an integrated silicone nipple-collar design—meaning zero plastic touches your baby's milk.
