This is Medela's "Harmony Manual Breast Pump & Calma Set." I purchased it about 4 years ago and used it for about 1 month. After that, it was stored in a cool, dark place at home. [Product Condition] • The breast milk valve (the white rubber part) has been replaced with a new one. Since the consumable parts that come into direct contact with breast milk are new, I believe you can use it with peace of mind. • Due to long-term storage, there is a slight yellowing on the plastic bottle part due to age-related deterioration. • Although it was used only a few times, due to the passage of time as mentioned above, I am offering it at a lower price than the market value. [Set Contents] • Everything shown in the first image is included. • The outer box is not included. [Shipping] • To minimize shipping costs, it will be packed compactly for shipping. • It will be washed and disinfected again before shipping. Thank you to those who understand that this is a used item and has been stored at home. Immediate purchase is welcome! Breast pump
