The Spectra Easy Breast Milk Storage Bags are designed for the convenient and safe storage of breast milk. Made from BPA-free, pre-sterilized material, these bags ensure that the milk remains safe for your baby’s consumption. Featuring a double-zipper seal, they prevent leaks and maintain freshness. The bags are durable, freezer-safe, and designed to lay flat for efficient storage, saving valuable space. Each bag has a writable surface to note dates and times, making it easier for parents to keep track of their milk supply. The Spectra bags are compatible with Spectra breast pumps, allowing for direct pumping into the bag for a hassle-free experience.
