INON Underwater Semi-Fisheye Conversion Lens UFL-G140 SD

Selling due to upgrade. I haven't used it in several years, so the cover has scratches and signs of wear, but the lens has no scratches that would affect image quality. The product includes everything shown in the images, and in addition to the lens, it comes with a front mask for GoPro 5-7 and a lens adapter for SD to ZD mount.
