I purchased this here and used it to obtain a certification. There are no markings. While there are no other noticeable scratches or stains, please refrain from purchasing if you are concerned about minor details, as it has been stored at home by a non-professional. It will be shipped in a plastic bag to prevent water damage. Please note that it will not be bubble-wrapped.
