This is a hands-free electric breast pump. It is sold as a set of 2, so separate sales are not possible. I used it about 5 times, but I stopped using it after my milk supply became stable. After use, I washed it with a neutral detergent and disinfected it with Milton. There are no noticeable scratches or stains, but please refrain from purchasing if you are concerned as it is a used item. All accessories are included, including the box and instruction manual, and it works as usual. I have confirmed that it charges without any problems. It was easy to use as it allows for hands-free pumping and has few parts to wash. - Brand: izxi - Model: YW-688 - Battery capacity: 1400mAh - Size: 143×112×87.6mm - Charging method: USB type-C - Accessories: Outer box, inner box, instruction manual, charging cable, storage bag - Price at the time of purchase: 6,980 yen
