It's a beautiful item, having been attached to a lens only once or twice since purchase. There are no scratches or stains on the lens. Product Name: Close-up Lens 500D/77mm Filter Diameter: 77mm Shape: Screw-in type. No accessories included. "This close-up lens allows you to easily enjoy close-up (macro) photography simply by attaching it to the filter thread at the tip of your lens." According to the manufacturer's description, it has a two-element, two-group design that effectively suppresses chromatic aberration, and is said to be a cost-effective one-element design. I will ship it in a round filter case. Please consider the filter case as a bonus.
