Stored at home. This is a used item. There is no warranty for used items. The instruction manual is included. Shipping will be at the buyer's expense. There were no noticeable stains, but please refrain from purchasing if you are a nervous buyer. As stated in my profile, I will refrain from responding to comments (price reduction, etc.) because I had an unpleasant experience in the past. Thank you for your understanding. Please note that I do not accept purchases on behalf of others.
