Matyz Glass Breastmilk Storage Bottles, 6 Pack – 6 oz, BPA-Free & Leakproof

Safe, versatile, and easy to use

Breastmilk safety is our utmost priority, and Matyz delivers a glass bottle system designed for everyday pumping, storing, and feeding. Made from borosilicate glass with a notably low coefficient of thermal expansion, these bottles stand up to boiling sterilization and freezer use, while remaining chemically stable and free from plastic-taste transfer. The result is a practical, glass-based option that supports your routine from pump to table.

Premium materials you can trust

• 100% food-grade borosilicate glass with very low thermal expansion, making it thermally shock resistant for boiling, freezing, and oven use.
• No harmful chemicals and no plastic taste transfer into milk, helping you feel confident in every pour.
• CPC Certified Food Grade for added assurance.
• Wide neck design for easier cleaning and everyday use.

3-in-1 wide-neck design for pumping, storing & feeding

• The clear sealing disk can be replaced with nipples, so you can pump, store, and feed from the same glass bottle and reduce transfers.
• Designed to work with most wide-neck pumps such as Spectra and Philips.
• For narrow-neck pumps like Medela, a bottle converter is included as a bonus gift for flexibility.

Leakproof, easy to clean, and clearly marked

• Screw-on lid and sealing disk prevent leaks, making them ideal for freezing, travel, flights, and camping.
• Clearly marked measurements help with consistent storage and feeding portions.
• Glass surfaces resist scratches and odors better than plastic, simplifying cleaning and reuse.
