This is an inner bag that makes it easy to keep baby bottles clean. I purchased it in 2025 and believe I used 2 or 3. I will not count the number of bags to avoid being unsanitary, so I will ship them without counting. Please be aware that the item has been opened and a few bags have been used. - Brand: Kansoon - Product Name: Inner Bags for Baby Bottles - Function: No need for sterilization or washing - Features: Easily keeps baby bottles clean
