Ski mask?Car fob on one "ring" (a cable "ring"); house keys, customer office keys, flashlight (Fenix that uses a 123A battery ; brighter than the BIL's much bigger and much more expensive flashlight), tiny multi tool on another; wallet; pocket pistol; a pack with wipes, masks, and tools (so I tell customers, as I'm not wearing a mask) that really has a full size H&K USP, spare mags for it, and spare mags for the pocket pistol. There may be a mask in there somewhere.
