Thank you for viewing. This is a set of 20 disposable inner bags for baby bottles. I purchased these, but I ended up not needing them as my child weaned off bottles before I could use them, so I am selling them unused and unopened. 【Product Condition】 ・Unused ・Unopened ・Stored at home (stored in a dark place) 【Product Features】 ・Simply set in a baby bottle for use ・Disposable, so no need for washing or sterilizing ・Convenient for feeding when going out or at night ・For 240ml bottles (with guide lines) Although unused, please understand that these have been stored at home before purchasing.
