This is a used item. This ring furnace was used by my father in dental technology, but I am selling it because he no longer uses it. It is being sold as a set with a deodorizing device, Labo Clean, etc. Please check the photos. Operation has been confirmed. Please understand the condition before purchasing, as there may be dirt, scratches, and discoloration due to use and storage. (The items in the images are all that is included, and they will be sent as they are m(_ _)m) Thank you very much!
