I bought this from an online store on a website overseas. It's new and unused. It's been over 7 years since I purchased it, and it's been stored at home. There are no scratches or stains, but there is a scratch in the area shown in the photos, which was there originally. - Size: 16 inches (41cm) 2.25mm - Brand: HS Sprenger - Type: Spike chain The size is probably suitable for small dogs.
