I purchased this new for my daughter, but she only used it for about six months. It has been used carefully, and I believe there are not many noticeable stains or marks. (There may be some stains or marks that I have missed.) My daughter has grown, and we no longer use it, so I am selling it. Please refrain from purchasing if you are sensitive to used items, as this has been stored at home. Returns are not accepted after purchase. The warranty has expired as it has been over a year since the purchase. Thank you for looking.
