This is the Pit Bull, the successor model to the Monster Dog. I own a large collection and haven't used this one heavily. The lenses have been replaced with new polarized lenses. There are no noticeable scratches on the frame, but the ear socks are slightly sticky. Although there is some wear and tear, I personally think it's a beautiful item. This is a discontinued model, so it's considered rare. This is a used item and my personal assessment. Please refrain from purchasing if you are sensitive to imperfections. It is also listed elsewhere, so it may be removed suddenly. Other models are also on sale.
