Items came right away and look great for replacement covers. Due to the way these were manufactured, they don't screw on all the way like the Shure covers due. Placing a rubber or neoprene O-Ring on the threads of the mic can solve this. It will act as a spacer to fill in the gap and will be what the cover tightens on, not the lip inside the cover. May also give some extra shock protection should you drop the mic. Please try not to do that!!!!
