The Kiinde kit allows milk collection, storage, and feeding from sturdy leak-proof freezable recyclable Twist pouches, which can twist onto pumps with included adapters, then seal securely with caps for refrigerator or freezer storage, and later fit into the bottle frames for feeding, collapsing as they are emptied to help eliminate gas in baby. Kit includes 10 adapters for use with Medela, Lansinoh, AVENT, Evenflo, Playtex, Ameda, Tommy Tippee, and Hygeia pumps; 2 plastic pouch-holder "bottles"; 19 Twist milk storage pouches; 3 nipples (slow, medium, and fast-flow) in cases; "Keeper" pouch holder/organizer that holds 12 pouches; and 2 nipple brushes (unused). Plus there are an additional 2 pouch-holder bottles and 7 additional nipples in cases. Everything is in excellent condition (though many of the bottle frames and nipple cases have been marked with a name for daycare use), and have been stored in a smoke-free home.
