Purchased in 2022. I didn't get much breast milk with the breast pump, so I didn't use it very often. Operation has been confirmed. I used the baby bottles to feed formula. The breast pump doesn't have a box, so I will pack it in a bag. The freezer packs for breast milk and the adapter are new and unopened, but the box has been slightly crushed during storage. Shipping will be in simple packaging. Also, I am selling on other sites, so I may suddenly delete the listing. Please understand. *All items for sale are stored at home. The products are evaluated from a layman's perspective. I inspect the items before listing and describe them, but there may be oversights. Please refrain from purchasing if you are looking for perfection or are overly sensitive. Returns, refunds, and complaints are not accepted. Also, I have two cats, so cat hair may adhere to the products. Please purchase with the understanding that this may occur.
