Keybladizer

I've used a two-key organizer every single day for the past year without encountering any issues whatsoever. It accommodates keys with a diameter of 24 millimeters and a width of 2.1 millimeters. You'll require six neodymium magnets, each measuring five by one millimeter, as well as four screws to hold it in place.
