Sounds super useful for tracing curves onto a material you need to cut. Is there still lead in it? Any health issues? Is that why I can't find them in North

Sounds super useful for tracing curves onto a material you need to cut. Is there still lead in it? Any health issues? Is that why I can't find them in North America? EDIT: I do find hits for Flexible Curve Ruler on Amazon but several reviews complain they don't hold their shape well. Are they made of a substitute that doesn't perform as well as lead?
