Good bottles that meet many needs
Lid fits well, doesn’t leak and doesn’t have a bad odor. The bottles are easy to clean and lightweight. They are marked up to 180 ml. We haven’t dropped them so I don’t know how they would hold up if they fall. We prepare bottles for the whole day and take them out one at a time everyday and have seen no wear and tear yet after 2.5 months. Bought these bottles primarily to avoid plastic as much as possible and the silicone part of the lid does the job of blocking any contact with the plastic part of the lid and the milk, which is great because other brands didn’t do that.

Perfect Storage Bottles
Love these bottles! High quality and they seal completely to make them leak free! Super easy to disassemble and clean. They even fit on maymom pumping flanges.

Buy these!
If you’re debating on getting these, do it! The bottles are very well made and perfect for storing in the fridge. I haven’t experienced any leakage, though I never fill above the 6oz mark. They’re easy to clean and don’t have that milky smell that plastic bottles hold. Highly recommend getting these for yourself or as a gift.

Perfect BM storage
I don’t have any bad things to say about it these! I use them daily for putting BM in after I pump at work. Love that they are glass. I’ve never had leaks

⚠️ Dangerous: Contains Lead — Do Not Buy!
I purchased the COMI Wide Neck Glass Breastmilk Collection & Storage Bottle (6oz, Gray Lids) expecting a safe, BPA-free solution for feeding and storing milk for my baby. What I found instead is extremely concerning and unacceptable — traces of lead have been detected in this product. Lead is a toxic heavy metal that can cause serious health issues, especially in infants and young children. The presence of any amount of lead in a product designed for feeding babies is absolutely shocking and dangerous. Despite the company marketing these bottles as safe and BPA-free, the lead contamination directly contradicts those claims and puts babies at risk. I strongly urge other parents and caregivers to avoid this product entirely. No amount of convenience or affordability is worth risking a child's health. It’s incredibly disappointing and frankly disturbing that such a product made it to market. Until the manufacturer addresses this issue and confirms their products are lead-free with certified third-party testing, I cannot and do not recommend this product.

⭐️⭐️⭐️⭐️⭐️ Great Quality and Super Convenient!
These COMI glass bottles are a must-have for pumping moms! The wide neck design makes them easy to clean and compatible with my breast pump and feeding nipples. I love the screw ring and re-markable sealing disc—such a thoughtful feature for tracking dates. They feel durable, are BPA-free, and give me peace of mind storing milk safely. The gray lids are a nice touch, too! They also fit in my Momcozy milk storage cooler, such a great value

Perfect replacement for my plastic bottles!
I’m trying to utilize less plastic with our new baby and wanted to replace my pump bottles/milk storage bottles. These have been great as they are comparable with my Spectra pump, hold a good amount of milk and seem very leak proof. The glass seems high quality for the price and was very clear/clean after use and wash. The only thing I didn’t think about was that they are heavier than plastic when pumping, but are still fine with a pumping bra.
