Great size and quality
Perfect for milk storage. The glass is thick and it comes in two different sizes.

Love but the lids
These are great for milk storage! The lids are where my issue lies. There is a small insert inside & it can get moldy if you don’t take it out. Also, a couple of the lids have cracked & broken just from washing & using them multiple times.

Do the job
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.

Bottles are not good quality
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.

Perfect size
We use these for everything not just milk. For snacks for baby food, etc.

👍🏼
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.

One of them was completely shattered, 2 were chipped and there bits of glass everywhere. I’ll still use the ones that survived once I can be sure I’ve gotten all the bits of glass off of them (I’ve already boiled, and washed in the dishwasher but I still feel grittiness) but I’m not loving the look of them or the quality as much as I was expecting.

One arrived broken, too inconvenient to ship back based on my location so just decided to keep the unbroken ones but no refund was given.
