I am selling it because I don't plan to use it for a while. Operation has been confirmed. The outer box and instruction manual have been disposed of, so only the item in the photos will be included. I will clean it thoroughly and ship it in a well-packaged condition. It is a beautiful item with a short usage history, but please understand that it is a used item. Please note that returns are not accepted.
