Thank you for viewing. This is the Medela electric breast pump "Swing Maxi Flex." It can be used on one or both breasts, and it's highly efficient, allowing you to pump effectively in a short amount of time. Operation has been confirmed, and the unit has been disinfected with alcohol. All accessories are included, such as bottles, tubing, and the power adapter (see photo 3). The original box and instruction manual are also included. It originally comes with two 150ml bottles, but I will include three more. Also, to make pumping both breasts simultaneously easier, as you would otherwise need to hold the bottles with both hands, I'm including a hands-free pumping bra. It's size S. My daughter used this for about a month to pump breast milk when she couldn't latch properly as a newborn. There are no noticeable scratches or stains, and it's in relatively clean condition, but please understand that this is a used item before purchasing. #Medela #SwingMaxiFlex #BreastMilk #BreastPump #BreastPumpingMachine #ElectricBreastPump #HandsFreeBra
