Thank you for viewing. This is a simple and easy-to-use Medela electric breast pump. It is USB rechargeable. I used it for about 3 months, but I haven't had the opportunity to use it for about 3 and a half years, so I have been storing it at home. During that time, the main motor unit would not turn on, and the warranty period has also expired, so I am selling the contents of the original set, excluding the main motor unit. I don't see any noticeable stains, but please refrain from purchasing if you are concerned, as it is a personal inspection and has been stored at home. I plan to disinfect it again before shipping. [Set Contents] ・Breast milk bottle (150ml) ・Multi-lid ・Bottle stand ・PersonalFit Flex Connector ・PersonalFit Flex Breast Shield M (24mm) ・Tube ・USB charging cable ・USB power adapter [Items not included this time] ・Main motor unit → Does not turn on. Box and instruction manual included.
