The Gilbert Molten Lead Casting Kit

The Gilbert Molten Lead Casting Kit allowed the adventurous you to scoop up molten metal and cast an army of glorious minions while ingesting your RDA of toxic poisoning.  And you thought Easy-Bake ovens and Creepy Crawlers and lead-based paints were hazardous.  We say ‘no’ far too often to kids.  They just wanna have fun without all the hassles.
