I purchased these items at a store and used the SS size for about a month and the S size for about two months. Since I was primarily breastfeeding, I think they are still in good condition. Please purchase only if you are comfortable with used items and understand their condition. The umbilical cord care set that comes as a bonus only had the disinfectant used, so the disinfectant is not included. Please let me know if you don't need it.
