Unsurprisingly, key organizers tend to get thicker as the number of keys contained increases, particularly if all contained keys are stacked in a single row. KeyDisk remedies this issue with a sleek triple-stack design that keeps up to six keys handy, making it the thinnest key holder to date at just 8 millimeters, and while it’s not the smallest we can definitely appreciate the difference thickness makes (think thin, large-screened modern smartphones). It’s also compatible with standard key rings, is easy to disassemble or modify thanks to both philips and flathead screwdriver compatibility, and weighs just 1.2 ounces thanks to an all-aluminum build.
