momcozy S9 Pro Breast Pump Set of 2 for Both Breasts - Brand: momcozy - Model Name: S9 Pro - Included: Instruction manual, charging cable, all parts - Color: Clear - Quantity: Set of 2 Thank you for viewing. This is a hands-free (portable) breast pump that I purchased in May of this year and used for a little over a month. It works without any problems. I was able to do housework and play with my child while pumping by putting it in my bra or top, so it was very helpful, even though I only used it for a short time. It costs about 17,000 yen when new. I hope the next person can use it a little longer. Regarding the parts - I used one spare valve, so only one extra will be included, but you can purchase them on Amazon etc. - One USB-C cable is unused. - I will wash and sterilize all the parts (or wipe them with sterilizing wipes) before sending them. I think you can use them with peace of mind even though they have been used. - The silicone has slightly discolored due to washing, but this is a natural occurrence with use, and I have confirmed with the manufacturer that it does not affect the product.
