Momcozy S12 Pro for both breasts, with extended warranty. Price negotiable. The diaphragms and duckbill valves have been replaced with new ones, so the suction power is like new. Spare duckbill valves (2) and cords (2) are unused. I disinfected it after each use. It is stored in a clean condition. Compared to new ones, the flanges may appear slightly cloudy due to use and storage, but there is no problem with use. Please understand that there may be minor scratches and stains as it is a used item.
