>>9081004>spinny Classics Prime's smokestacksFunny you mention that, mine was missing one for the last year or two until it came up in the bottom of a bin while organizing recently. Unless you throw your transformer in an oily puddle or something I doubt there's much outside that's going to damage them in the five minutes or so it takes to walk outside and snap a pic, at least in my experience. If there's ever a smudge of dirt or whatever a wet qtip takes care of it quick.
