These breast pump collection cups and storage bags work together to make pumping easier and more convenient. The cups are lightweight at just 2.7 ounces each and feature an anatomically designed shape to help you pump more milk in less time. They work with popular Medela pumps like the Freestyle Flex and Pump in Style with MaxFlow, and come with only three parts for quick assembly and cleaning. The storage bags feature a durable double-layer design with a secure double-zipper seal to prevent leaks. They are pre-sealed for hygiene and come ready to use. The bags stand on their own and include a large area where you can write the date and other important details. With a flat profile design, they save freezer space and thaw quickly when you need them. Both products are made from food-grade, BPA-free materials and work together to support busy mothers who want reliable, practical pumping solutions. Each cup holds up to five ounces, and the storage bags come in six-ounce sizes, giving you flexible options for collecting and storing breast milk at home or while traveling.
