AIR WING Air Wing Wind Direction Adjuster

This is an air wing that attaches to the bottom of an air conditioner to adjust its airflow, measuring 50.4cm x 16.4cm.
The adhesive part has been partially removed using a sticker remover, so if you clean it with something available at a home improvement store, it can be used without any issues.
The fifth photo shows that the package was damaged upon receipt, and I repaired it with adhesive, but it has been usable without problems.
