【New 4-Piece Set】Air Conditioner Sterilizing Agent (Refill)

Product Name: Barrier CLEAR (Refill)
This is a refill for an air conditioner attachment product that claims to remove viruses and bacteria, and deodorize.
The item is new and unopened. However, out of the four units, one has a dent on the top of the package (see 3rd photo), and another has a part of the package surface peeling off (see 4th photo).
We kindly ask for your understanding regarding these points if you decide to purchase.
Thank you for viewing until the end.
