Drying method: Electric Ozone deodorization Clothes dryer I purchased this several years ago but never used it, and it has been in storage. It is new and unused, and I have only checked the contents, so I have not confirmed its operation. Please understand this before purchasing. The outer box has dents and stains. Please check the photos. It was stored in a storage space, but the outer box has dents, etc. If you would like to confirm its operation, please comment. I will wrap the outer box in bubble wrap for shipping. No smoking or pets. Thank you.
