Hi /3dpg/! What materials are safe for handling a lot with bare skin?

I'm a digital/semi-trad sculptor learning anatomy. I sculpted a skeleton in blender and had a local service print it so I could use sculpey to add/learn muscles. I improved my skeleton in blender and want to print it again bigger, but since then I've heard some popular filament materials are toxic, even after they're cured. I'm going to be handling this a LOT, maybe even giving copies to kids in my family, so I need it to be safe. Ridges are ok if they're sub-mm, but the higher the resolution the better.
