THE MASON BOTTLE SYSTEM
Made to Work Together
Every Mason Bottle jar—from glass to insulated stainless steel—is built to the same regular-mouth spec, so nipples, lids, sleeves, and drink tops mix and match across the entire system.
Start with bottles for those first feeds, then simply swap the top as they grow. Store milk, pack snacks, serve meals, or transition to a kids’ drink bottle, all without replacing the system or filling your cabinets with more gear.

“I ordered these to help store milk, especially while I am pumping at work. They do not yellow and get gross like plastic does. I feel like my milk is safe and secure in these.”

OUR STORY
Why we Started Mason Bottle
As new parents, we wanted to make more intentional choices about the products we brought into our home. That meant reducing plastic wherever possible, prioritizing sustainable materials and choosing fewer, better essentials designed to serve more than one purpose.
