100% Satisfaction Guarantee

We are the only bottle brand where you can return any product, at any time, for any reason.
Top Benefits
Safe to Freeze, Safe to Warm
Freeze breastmilk or baby food - or anything really. To reheat a frozen jar, simply thaw on the counter, in the fridge or in a bowl of luke warm tap water.
All jars will break if taken directly from the freezer to high heat, but as long as you thaw the jar first, heat is no problem.

Easy to Clean and Easy to Fill
Our jars naturally have wide, easy to fill openings without shoulders that trap milk and require bottle brushes or special cleaning tools. This not only cuts down on clutter, but allows you to fill the jars frustration free!
