Qmibaby Glass Breastmilk Storage Bottles 180ml 6oz BPA-Free Leak-Proof Natural Baby Bottle Wide Neck with Screw Ring Sealing Disk for Breastfeeding Grey 4 Packs

• Premium Borosilicate Glass: Crafted from food-grade borosilicate glass, our breastmilk storage bottles are 100% BPA-free, lead-free, and free of harmful substances-no plastic odors or residue seeping into breastmilk. The upgraded shatter-resistant design withstands daily drops, avoiding safety risks from broken glass, while maintaining glass's natural ease of cleaning. Suitable for refrigeration, heating, and room-temperature storage, keeping breast milk safe at every step
• Universal Compatibility: Glass baby bottles are designed with a wide neck that fits most major breast pumps (including Avent, Spectra S1/S2, and more) and all standard wide-neck nipples, these bottles eliminate the need for milk transfers. Pump directly into them, store without leaks, and attach a nipple for feeding-cutting down on extra tools and wasted milk. Convenient for busy moms juggling breastfeeding tasks
• Optimal Capacity: These natural baby bottles are perfectly sized for most feeding or pumping sessions, balancing portability with enough volume to avoid frequent refills. The clear 10ml incremental markings (finer than 15ml markers) let you track milk volume accurately, while the writable silicone lid works with pencils-easily mark dates, times, or names, then erase and reuse, keeping storage organized
• Leak-Proof Design and Easy Cleaning: The reinforced silicone sealing ring and tight-fitting lid ensure zero leaks, even when tossed in diaper bags. The wide-neck design and fully detachable parts (lid, ring, sealing ring) leave no hidden gaps-clean effortlessly with hot water, steam, or top-rack dishwasher. No more stubborn milk residue, making daily maintenance a breeze
• Care Tips for Long-Lasting Durability: Use soft bristle brushes or sponges for cleaning to avoid scratches on the inner walls. Sterilize by boiling in water for 35 minutes or using a steam sterilizer. Store in a dry, cool place away from direct sunlight, and handle with care when empty to maintain shatter resistance over time
