Wide Neck Glass Breastmilk Collection Bottle - Safe Borosilicate Glass

In this review the COMI wide neck glass breastmilk collection and storage bottle is assessed as a simple, safety-focused option for pump-to-feed convenience. It is best for parents who want a nonplastic container that can be used for pumping, storing and feeding without transferring milk between vessels. The single biggest reason to buy is the food-grade borosilicate glass body that resists odors and residue, so breast milk stays pure and easy to handle. The review considers real user feedback on fit, cleaning and occasional leakage concerns.

Key Features

• Food-grade borosilicate glass: Keeps milk free of plastic smell and is safe for refrigeration, heating and normal storage temperatures.
• Three-in-one wide neck design: Allows pumping, storing and feeding with the same bottle to reduce milk transfer and waste.
• Screw ring with sealing disc: A silicone sealing disc provides a leak-resistant closure and a writable surface for dated notes.
• 10 ml measurement increments: Fine measurement marks make it easy to track how much milk was expressed and stored.
• Disassemblable parts: All components can be taken apart for thorough cleaning to avoid residue and maintain hygiene.
• Durable construction: Thicker glass reduces breakage risk during normal use and cleaning compared to thinner glass bottles.

Who It's For

The COMI glass bottle is ideal for parents who prioritize avoiding plastic contact with breast milk and who want a bottle that fits common breast pump flanges for direct collection. It is useful for those who value easy cleaning and want a bottle that can move from pump to fridge to feed without transfers.

Parents who need ultra-light travel gear or want an insulated, shatterproof system for rough outdoor use should look elsewhere; while the glass is thicker than typical glass bottles, it remains glass and benefits from careful handling.

Pros & Cons
