Pink circular breast pump with USB cable. I used it for a short period, but I no longer need it, so I'm selling it. You can pump while doing housework. It's very easy to use! I used to sterilize it with steam. Although it's at your own risk, it seems to be fine for now. Usage period: About 1 month Frequency of use: About 1 to 2 times a day. After washing and drying, there are what appear to be water spots that won't come off, so please check the photos. The battery lasted 2-3 days, as I didn't use it very often! I think you can pump 3-4 times on each side with one charge. I have confirmed that it works, but please understand that this is a layman's inspection and confirmation, and that it is a used item, so please be sure to check the photos and only purchase if you understand. Returns and refunds are not accepted after purchase. Please be aware of this. If you would like to see other parts or need photos of specific areas, please feel free to comment. After washing and steam sterilization, I have stored it in a zipper bag, and I plan to ship it back in the original bag or box. Instant purchase is welcome! - Color: Pink - Accessories: USB cable - Shape: Circular - Function: Breast pump Thank you for viewing.
