The wide plastic tube that Peterson ships many of its tools in (and that you can also purchase separately, albeit with a large minimum order quantity) is also ideal for storing the standard six-die set of dice used in many tabletop role playing games. I suspect the overlap between physical security nerds and TTRPG players is significant enough for this to be rather useful.
Not a member of this community but I clicked the picture because I used to manage a machine shop. We discarded a hundred of these a day. Usually in red, green, blue, and clear depending upon the tool manufacturer.
