Manufacturer: Hero (Hard Type) Diameter: 235mm Set of 10 discs. K9 DISC JAPAN logo disc. Although new and unused, there may be minor scratches from storage. Will be shipped directly in a cardboard box. Also, I have a dog. I pay close attention to prevent dog hair from sticking, but it is difficult to completely prevent it. Please be aware if you are overly concerned or have allergies. Thank you.
