This is a set of four HAKUBA 58mm filters with a carrying case. These filters were used frequently, so they show considerable signs of use. All four filters have minor dust-like dirt and streaks from wiping due to coating degradation, but I don't think they will significantly affect image quality. The set includes the following: 1. MC Lens Guard 2. MC Skylight 1B 3. MC UV 4. Circular PL (Polarizing) Sample images in the order listed above are included at the end of the product images, so please refer to them.
