This iPhone 6.7" kit designed to fit Pro Max and Plus sized iPhones with MagSafe arrived with the 67mm filter mount, a 67mm variable ND2-32 (Neutral Density) filter, a cleaning cloth, a case and some L shaped sealing anti-slip strips. It came with no instructions but is straightforward to attach although if your phone has a case with a raised protection border around the cameras then the case will likely have to be removed before you can use it. If the camera hole had been a couple of mm larger it would have worked with my case on, but such is life and I'll have to remove it every time I want to use the filter adapter. I have not used the anti-slip strips as I suspect they would stop my case from going back on after use.Once attached to the phone via the MagSafe interface any 67mm round threaded filter can be used. In my case it came with the variable ND filter which needs to be screwed in tight otherwise it comes loose when you try to twist the bezel anti-clockwise to adjust the light entering the camera. Other than that it works very well. It also has magnets on the outside so you can attach other accessories on top of it which is a nice touch. The slight annoyance of having to remove my case when I want to use it aside, I think that it's a great quality adapter and would not hesitate to recommend it.
