Action Camera 22mm Lens Protector/Adapter Ring

A lens protector ring designed for wide-angle action cameras. It can be installed on all action cameras with a lens outer diameter of 22mm. It protects the protruding lens from accidental scratches. It is divided into an adapter ring and an outer cover for better lens protection. The adapter ring has an inner diameter of 37mm. The small pitch outer thread cannot be achieved by printing. This inner diameter is slightly smaller than the filter thread outer diameter, allowing the filter to be violently screwed on for use.
