Mason Bottle 8oz Breast Milk Storage Jars (12-Pack) – Reusable Glass Baby Food Containers with Lid for Baby Formula & Breastmilk – Airtight, Stackable, Freezable

Perfect for milk storage. The glass is thick and it comes in two different sizes. I’ve owned these for 5 months now and they are durable and good quality. They’ve stand the wear and tear of washing and sanitizing

The Mason Bottle Breast Milk Storage Jars are an excellent, sustainable choice praised for their high-quality, durable glass construction and airtight, leak-proof lids. They transition seamlessly from breast milk to baby food storage. Highly recommend these jars for their safety, convenience (freezer/dishwasher safe), and practical design, despite minor concerns about the lids being difficult to open and the jars taking up more storage space than bags.

We love these jars, I use them to store my baby’s breast milk. The seal on the lid is great. I also like that the little rubber part pops out of the lid for more thorough cleaning

We use these for formula feeding and our toddlers everyday cup. Unfortunately 2 jars did break when we used the bottle warmer.

These are fantastic. After using them for a while, I use the 4oz ones way less than I do the 8oz jars. But I’m enjoying them. One lid did develop mold under the seal ring, but that was a genuine surprise - usually they air dry fully on the drying rack very easily.

I really wanted to like the mason bottle line, but there are flaws in the bottles, plastic rings and more severely the nipple. The nipple: These slow flow nipples drip just as quickly and the medium flow nipples. This causes choke issues while feeding your newborn because the flow of liquid is still too fast. The bottles/ lids: the bottle threads are not perfect so they leak with the plastic rings unless you apply full force pressure and tighten and check them every time. The bottles themselves, I’ve had two break by cracking at the bottom. They are not mason jar hefty and if you warm them up with sink warm water out of the fridge they are more likely to crack at the bottom.

As a grandmother I have these for my DIL when they visit from out of state. Perfect for breast milk storage but also for food storage as baby grows. They are the right size for small portions for toddler whether they are frozen or refrigerated. No matter what you have in them they won’t leak in your cold storage bag or diaper bag.

These jars are awesome! The assorted colored lids are a nice touch and make it easy to distinguish between them. The smaller jar's size is a bit awkward, and it can be tricky to gauge the milk level since they need to be filled beyond the last measurement line. Pouring could be smoother if the mouths were narrower, but we've adapted. The plastic lids require a tight screw, but the containers themselves are durable – they even survived a fall from my fridge! Overall, they're incredibly handy.
