Metals are fascinating because the ability of their electrons to fly around all over the place. This makes them conductive, malleable and ductile. But instead of using them for electronics, we can actually use them to adorn ourselves and make ourselves feel good. Because what's outside might eventually diffuse into their whole bodies. I don't really care. I just like these because they're pretty and they're small. Everything is just fascinating when they're miniaturized. You can't do this with wood, right? I love metals ^_^
