01
Add it when your bag of wrapped glass arrives
A subscription starts after your first bottle order, so the right parts arrive before the old ones feel worn.
Fresh nipples until your baby's ready for a cup.
Replace what's gentle and important, not the whole bottle. Monthly nipple shipments help keep feeding fresh while the wrapped glass bottle stays in your routine.
How it works
Every few months, Ronini sends fresh nipples in the flow your baby needs.
02
We ship every 2 months
Fresh nipples and flow pieces arrive on a simple cadence you can adjust anytime.
03
You confirm before each ship date
We send a reminder before billing so you can change flow, skip, or cancel.
04
Subscription ends when your baby is ready
Pause or stop whenever your little one graduates to a cup.
Growing, gently paced
The number of polish shipments depends on when you started
Nipples are matched by month, so each shipment follows your baby's feeding rhythm.

Baby's bottle grows
Bigger bottles, when your baby's ready
If your baby is 4 months or older when a shipment is scheduled,
we bundle a 240ml Wrapped Glass 2-pack into that delivery. It
replaces your 160ml bottles — your total bottle count stays the
same.
- Ships with Stream nipples pre-installed (manufacturing constraint). On a different flow? Swap it in your portal before the box leaves and we'll include the right ones.
- Same heads-up as always: email and text 7 days out. Confirm, delay, or skip.
Smart Flow
Calibrated by pace, not age
Four flows, named by pace - not age

Most bottle nipples are described by age. We name ours by pace so you can match your baby's actual feeding rhythm.
Built around the Wrapped Glass.
One bottle body that protects glass, plus the fresh parts your feeding routine needs.
From the ground up
The Duo
Two bottles, two useful sizes, one clean glass path.
Per shipment
Replace only what needs replacing each month.
That never changes - your shipment quantity always mirrors your initial purchase.
Squeeze, refill, repeat.
A glass bottle stays protected in a soft wrap. Fresh nipples and venting pieces keep the feeding path feeling new.
