Thank you for viewing. I used this for about six months. I used it a few times when going out, and I kept it by my pillow in the morning to keep the milk warm while breastfeeding. It was very convenient, especially when going out, as I didn't have to bother making milk outside. There are no noticeable stains or damage, and I think it can still be used. It comes with the instruction manual, charging cable (unused), and box. Please purchase only if you understand that this is a used item.
