It is essential to ensure the safety of breast milk: the bottle body is made of food-grade borosilicate glass. While ensuring that it can be refrigerated, heated and stored at normal temperature, it does not contain any harmful substances, and there will be no plastic smell seeping into the baby’s milk (the penetration of harmful substances will lead to plastic smell). There is no need to worry about the safety of breast milk. All parts can be disassembled for cleaning.
Three-in-one wide-necked glass bottle is used for pumping, storing and feeding: the bottle is suitable for the Breast Pumps & Nipples, so mothers can pump, store and feed with the same glass bottle to reduce the transfer of breast milk and save precious breast milk.
100% leak proof and 10 ml fine measurement mark: silicone sealing disc is used, so there is no need to worry about leakage; The bottle has a 10 ml increment measurement mark. You know how much milk you produce. The ballpoint pen can be written on sealing disk to mark important matters. The mark can be erased and marked circularly.
It can ensure the safety of infants and young children: The bottle has a strong resistance to falling. When used, it can not only guarantee the use time limit of the bottle, but also avoid the safety hazards brought to infants due to broken glass. Glass bottles are not only healthier for infants, but also easier to clean than plastic bottles, because glass bottles are unlikely to leave residue and odor scratches.

⭐️⭐️⭐️⭐️⭐️ 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 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.

⚠️ 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.

Amazing.
08/17/25 I got these for breastmilk. They are so pretty. Sure you can use them for any other stuff. Silicone is very soft and good quality. The led is also great material and no cheap plastic. No need to extra tighten to avoid leaking.9/26/25 well the quality of the glass it amazing. The major down off is that if you are a type that actually scrubs and used very hot water for your dishes. I would warn you that you will end that scraping off the measurement from the glass.

Fragile so be careful!
The feel of this bottle is like a beaker in science class. It’s pretty fragile feeling and one drop will absolutely shatter this bottle. Keep in mind it is a wide mouth top like a mason jar, so pouring the milk out takes coordination or it will spill/leak. Haven’t had issues with the markings fading but I haven’t been scrubbing the outside much. I’ve used in the sterilizer & dryer machine with no issues.
