High Quality and Easy to Wash!
I’ve been using these for a little over a year now and they have held up great! Now that little one is older, I use it to store snacks or overnight oats, etc. Easy to wash/ dishwasher and very durable. I love how it’s glass and how the lids don’t rust like the originals. Worth the money!

Jars with multi-use functionality, safety, and durability
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.

great quality
i use these to store my extra breast milk in before bagging to freeze. work great! would definitely consider buying the nipples to go with it so i can just warm up and freeze!

100% would recommend
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

Practical even after breast milk stage
I love these! They were great for storing milk but I love the practical use after of being able to store snack and food in them after! Such a great buy and so sleek looking! Only thing be careful with the lid, if you’re too rough they can crack and break!

NOT GOOD for Breastmilk
So many flaws with these bottles. Do not use if you’re considering for Breastmilk for the following reasons: 1. Mouth is too wide so milk spills everywhere when trying to pour. 2. The cap is poorly designed so bottles don’t actually stack, they shift around and move when put atop one another. 3. The silicone gasket inside has no way of being removed so milk and moisture get trapped behind it…perfect place for bacteria to grow. So disappointed in these bottles. Fine as a mason jar but not for breast milk storage, which is what they are advertised as.

👍🏼
I only use these for storage because I hated them as bottles. I had issues with the nipples/rings leaking. But! I love these for food storage, the lids are cute, and they're easy to clean.

Excelente caldidad.
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.

Lo mejor para almacenar leche materna
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
