I'm selling this item because I no longer need it, after using it for about a year. It's an older model, but you can adjust the rhythm and strength with independent dials! It can be used with either batteries or an AC adapter. Due to a loss, all the parts are shown in the second photo. (The parts circled in green in the third photo, such as the bottle and stand, are not included.) There is a crack in the silicone valve due to cleaning, but it was still usable for expressing milk without any problems. Please check the sixth photo. The box and instruction manual will be included when shipped. Please understand the above points before considering a purchase. Electric breast pump, premium model. - Brand: pigeon - Model: Premium Model - Electric: Electric - Included Accessories: AC adapter - Parts: Breast pump body, hose, flask, cup Thank you for looking.
