I've decided to sell this as I haven't used it much. All accessories are included, and there are no scratches or stains. I used it a few times over about a year and stored it away from humidity. Please buy it now. I will contact you. If you have any questions, please feel free to ask. *Please refrain from purchasing if you are sensitive to items stored at home.
