Instant purchase OK! Inner bags for baby bottles, no need for sterilization or washing. There were 20 bags in the package. 9 bags remaining. Since they have been used once, I'm selling them at a low price. If you don't mind, please consider purchasing. Regular price is around 600-700 yen. They were convenient to have when traveling. I think they can also be used as disaster preparedness supplies for families with babies. - Brand: Kaneson - Product Name: Inner Bag - Usage: For baby bottles, 240ml - Features: No need for sterilization or washing Type: Baby bottle related goods
