Why can we do it?

This service was created because of our rental service.
⇒More than 100 pieces of GORE-TEX® clothing were ruined before the service started.
⇒This method was developed through many failures because the rental clothes could be used for research and development.
⇒Therefore, the concept of this service is different from that of a regular dry cleaning service.
