Red antique Chinese (?) box with MERCURY-based paint! 17,000 ppm Mercury! This is very dangerous! (I learn new things every day!)
Vintage curio box with R and Rooster on brass lid: 205 ppm Lead in the lid (90 ppm & up is unafe for kids.)
Who has a trinket box like this at home? This is from Kashmir, India: 192,500 ppm Lead [90 ppm is unsafe for kids.]
