Electric 2-Phase Breast Pump, Yellow Used during the newborn period, but as I wasn't able to produce breast milk, it has been fully sterilized and stored. It's a Medela electric 2-phase breast pump. Operation has been confirmed. It's convenient as it can be used portably with batteries. All parts and the instruction manual are included. You can pump and store the milk in the refrigerator with the lid on, and it also comes with a nipple, so you can feed the baby directly from the bottle. Spare valves and the strap are unused. I'll also include a Pigeon nipple shield (size M, I think) and a nipple aspirator as a bonus. I will wrap it in bubble wrap, pack it in a cardboard box, and ship it via Yu-Yu Mercari Bin or Raku-Raku Mercari Bin. - Brand: Medela - Model Name: Swing - Included Items: Storage bag, all parts - Function: Electric 2-phase pumping - Color: Yellow Thank you for looking.
