This is a set of four Kenko filters with a carrying case. These filters were used frequently, so they show considerable signs of use. The set includes the following: 1. Skylight There are small scratches and clouding on the coating. This may slightly affect image quality. 2. Polarizing PL Slight peeling of the polarizing film is visible on the edges. Tiny dust-like particles are visible. This probably has little to no effect on image quality. 3. Y2 Small scratches and dust-like particles are visible. This probably has no effect on image quality. 4. YA3 Two scratches, about 10mm long, are visible. Tiny dust-like particles are visible. This probably has no effect on image quality. Please refer to the sample images at the end of the product images.
