Medela Harmony Manual Breast Pump Essentials Pack This is a breast pump from Medela. It is a manual breast pump. Used a few times. Sterilized. I believe all the set contents are complete. The changing pad is available in two sizes: 45cm x 66cm and a mini size of 45cm x 33cm. Both were given to me, and while they have been opened and used a bit, it seems like almost all of them are left, with only a few sheets missing (I didn't count the number of sheets). Please refrain from purchasing if you are sensitive to used items, as this is stored by a private individual. Instant purchase is OK.
