A couple things.
First, don't eat it, lick it or put it up your nose (or other nefarious places) . I know, that sounds silly, but quite frankly almost all of the warnings about the "bad stuff that'll kill you from China" boil down to idiots (and 2 year olds) putting stuff like this in their mouth. A few years back one of my kids shoved a miniature head up his nose... That took a bit to get out, and yes, he was two.
Remember all of the hoopla over Chinese kids toys? --- Kids put EVERYTHING in their mouth which is why all of the materials used (like paint) have to be non-toxic.
BTW, ever wonder why the
GW model boxes say 14 or older? Simple: 14 year olds generally don't put this stuff in their mouth. Quite frankly most of the "recommended for" age ranges on things boil down to what is "normal" behavior for a child at that age level. This might be a fun read:
Age Determination Guidelines for children's toys So,
don't eat the miniature. Next, wash your hands after handling one before it's been painted. This goes for resin, metal, etc. Again, you don't want mold release to end up in your blood stream. For example, you get a brand new miniature, put it together then go eat a hamburger. In this case you're likelihood of getting sick is extremely small...but still possible.
That said, god knows how many things we touch on a day to day basis (door knobs, etc) that a hundred other people may have recently touched; some of whom are likely carrying a virus of some sort. So if you aren't washing your hands regularly you'll end up sick from something anyway. Heck, your white blood cells are probably fighting off a little something you got while you were in the bathroom earlier.....Which is exactly what your body normally takes care of without you consciously knowing about it.
From a historical perspective, people started getting sick far less often and living longer when they started washing up regularly...
None of this has anything at all to do with whether the model is a Real (
tm)
FW model or a recast. It also doesn't matter if it's "white" metal, lead, resin, plastic or whatever. The main thing is that you take the exact same precautions working with these mini's as you would going to the bathroom: Don't inhale the stuff, don't eat it and wash your hands afterwards.
