The bottle that doesn't

Medical-grade borosilicate glass inside. LSR overmold outside. Patent-pending venting system that actually works.

Zero Plastic Touches Milk
Every milk-contact surface is borosilicate glass or medical-grade silicone. No plastic vents. No plastic collar.
Shatter-Safe Design
Drop-tested and parent-proven. The LSR overmold absorbs impact and contains glass if it breaks - no shards, no mess.
Patent-Pending Venting
Dual venting reduces air intake during feeding. Less swallowed air, calmer feeds.
Two Variants. Different Jobs.
Glass + silicone overmold solves what each category alone cannot.

The Wrapped Glass Bottle
Patent-pending dual-vent system. Reduces air intake during feeding. Free for subscribers in Box 1.
learn moreThe process.
Every milk-contact material is named, sourced, and tested before it ships. Nipple geometry was iterated against IBCLC clinical input until feeds landed in the 15-20 minute window. Drop tests, thermal cycling, and lot-level certifications run on every production batch. Nothing leaves the factory unverified.
Slow is the cost of doing this right.
What joining gets you.
Specific perks, not vague stay-in-the-loop language.
Works with both 160ml and 240ml bottles. For every waitlist member, no minimum.
Real scarcity, not invented. When 500 hit, the perk closes — the waitlist stays open without it.
Order before the public launch on launch day. Skip the day-one crush.

September 2026 in the US. Waitlist members get 24-hour early access before the public launch.
Two variants share the same milk path.
Shielded— borosilicate glass with an injection-overmolded LSR silicone exterior. Permanently bonded under pressure, not a sleeve or spray-on coating.
Pure— plain borosilicate glass, no overmold; heats faster in a bottle warmer. Both ship with the same IBCLC-designed LSR nipple. The patent-pending venting system is compression-molded medical-grade silicone — sold separately or free with subscription.
Yes. Borosilicate glass is non-reactive, non-porous, and doesn't leach chemicals when heated, sterilized, or repeatedly washed. It's the standard glass used in laboratory beakers, Pyrex cookware, and now Ronini baby bottles. It also doesn't release microplastics — unlike polypropylene baby bottles, which can release millions of particles per liter when heated.
Spray-coated glass bottles spray silicone onto a finished glass bottle — surface adhesion only, uniform thin coat, can degrade or separate over time. Ronini's injection overmolding bonds silicone to the glass under high heat and pressure during manufacturing. The bond is permanent (chemical + mechanical), and thickness is non-uniform — engineered to be thicker at impact-prone areas like the base and shoulders.
Four concrete things: a free venting system with the first order ($10 value), 24-hour early access before public launch, a free diaper bag for the first 500 waitlist members, and ongoing email with feeding content plus production updates as launch approaches. No ads, no spam.
United States at launch. International shipping comes after the first US launch window. International waitlist signups are welcome — updates go out when the timeline is real.
Yes. The nipple shape was developed with IBCLC input — 20 Shore A LSR with a wide base and gradual slope to support a breastfeeding-compatible deep latch. Many parents use Ronini specifically to protect latch while moving between breast and bottle.
Yes — all components. Borosilicate glass and LSR silicone tolerate repeated dishwasher cycles (top rack), steam sterilization, and boiling water. The bonded LSR overmold doesn't trap water or grow mold.
