Mason Bottle 4oz Breast Milk Storage Jars (12-Pack) – Reusable Glass Baby Food Containers with Lid for Baby Formula & Breastmilk – Airtight, Stackable, Freezable (Deep Ocean)

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.

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

Using for breast milk storage, very useful. Tops fit other jars of the same size. I did have one break when I dropped it and one top crack. But they are pretty thick glass.

Overall, I like these cups well enough, but the gasket on the lids is hard to keep on which makes cleaning a little more challenging.

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

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.

Great for breast milk storage. Freezer safe. Dishwasher safe. Seal is great as long as plastic seal is in place. Not easily broken.

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.

Se sienten de muy buena calidad el vidrio es grueso, la tapadera hermetica me parece bien precio por los 12 botecitos. Yo los quiero para guardar mi leche materna, me llegaron en perfecto estado, el unico pero que pondría es que duraron 1 semana en llegar.

Llegaron en tiempo y forma vienen muy bien empacados y se ve muy buen producto

Me encantaron, los súper recomiendo!!!

Los bottles son de muy buena calidad, las tapas traen su empaque para evitar derrames, los tamaños son muy buenos, pensé que los de 4oz serían muy chiquitos pero son ideales para meter las papillas cuando salimos de paseo, todos llegaron intactos y venían muy bien protegidos en la caja. Son un poco caros si sumamos gastos de envío y cargos por importación, pero vale la pena tenerlos y así no contaminar tanto con el uso de las bolsas

Gran calidad, los sigo usando .
