Now protect your "liquid gold" with the first reusable breast milk storage bags that stand-up on their side and are easy to use & clean. Unlike silicone reusable storage bags that don't stand up, are hard to fill & pour from and retain odors, Baby Brezza's Reusable Breastmilk Storage Bags stand up on their own, have a 5.5"-wide side opening that makes them easy to fill and clean and don't retain scent. Each milk storage bag is 100% leak-proof, including a 100% leak-proof double zipper to close the side opening and a 100% leak-proof twist-spout for easy pouring into a bottle, just like a baby food pouch. Each package comes with one filling funnel that holds the bag open, making it easy to fill one-handed. The large side opening makes it easy to clean the entire bag with no hard-to-reach corners! Plus you can label the bags over and over again - just use a permanent marker which can be gently scrubbed off with water, soap and a scouring pad. Each bag holds 7 oz and has 0-7 oz measuring marks on the side. They are made from food-grade plastic that is safe for the dishwasher and freezer! Also safe to use in bottle warmers and washers (wash/dry cycles only). Phthalate-free and lead-free. Each package includes 10 reusable pouches, 10 twist-spout caps and 1 easy-fill funnel.
