Thank you for viewing. This is a Pigeon electric breast pump, the "Mother's Milk Assist" model. I purchased it in September 2025 and used it for a few days while my child was hospitalized. I mostly sterilized it with chemical solutions. After the last use, I sterilized it with steam and have stored it. The silicone parts have little yellowing, possibly because I didn't sterilize it with heat very often. It's easier to express milk with this than with a manual pump. The following items are included: ・Spare silicone valve: 1 ・Breast milk freezer bag adapter: 1 ・Freezer bags (40ml): 12 The original "Mother's Milk Real Feeling" baby bottle (160ml) that came with it is currently in use and is not included.
