Kenko Step Down Ring 58mm-52mm, Plastic Case

This is a ring for attaching a 52mm filter to a 58mm lens. Depending on the combination, vignetting or other issues may occur. This item has been stored at home unused since purchase. The outer cardboard box has damage such as scuffs, dents, and tape removal marks. The plastic case is not a genuine Kenko product; it was something I had on hand.
