Medela pump in style barely used sanitized with two sets of 24 mm flanges and one pair of 27mm flanges. Two small collection bottles and two small colostrum bottles as well as a small pack of sanitation wipes and an extra frida breast engorgement mask. This pump has a battery pack included for outlet free pumping. If I am able to, I will include the rechargeable batteries I purchased for this but I will have to check with postage! As always you should sanitize before use and replace the silicone parts as needed. Expect water marks from washing thoroughly!!
