A set of various action camera accessories. I received this as a gift, so I don't know the detailed specifications. Please check the images for details. When I took the camera body out of the case, it was sticky, so I wiped it with an alcohol wipe. The stickiness is gone, but I couldn't wipe it off completely in the details, so please refrain from purchasing if you are concerned. There is a head-mounted belt and a body-mounted belt that seems to be usable on a motorcycle, etc.
