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.

Great product. NO LEAD - reviews are wrong. Confirmed myself
I bought this product, loved it, went to buy more and out of curiosity saw the reviews. Some people warned about lead content which freaked me out. So I bought a legitimate lead testing kit and saw nothing. I also messaged the seller to send their heavy metals report and it showed nothing. Not sure if the person who tested it and put a scare review had a faulty kit or it’s another seller in competition trying to ruin this brand’s reputation, but I didn't see any lead. Such a shame the reviews freaked out me and prevented other buyers from getting this for no good reason. Great product and will buy again. I like that it’s glass and a large volume and fits my Spectra pump perfectly so I can pump directly in it. Would recommend.

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 for Momcozy milk chilling system
I got these for my Momcozy milk chilling capsule to replace the plastic bottles that it came with and they fit! They actually fit in the capsule a little more snug than the plastic bottles, but I like that because things rattle less. I feel like the glass is not only safer for my milk but also cools my milk faster than a plastic bottle would. Easy to use and clean! Zero leaks. The glass hasn’t shown any signs of cracking or breaking and they have traveled now on three different flights and have been on multiple bouncy car rides. The labels are easy to read and haven’t shown any signs of wearing off.

⭐️⭐️⭐️⭐️⭐️ 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

⚠️ 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 for mixing formula
We love these for mixing formula in. The glass bottle is nice because it heats up quickly and has a 6oz capacity. The plastic version of these fit my spectra pumps, I haven't tried the glass because I don't want to break them if they fall but imagine it would fit for those as well. Good value for the price.
