Stainless steel is mostly nonmagnetic. The whole point of these toys is that they're made of very strong neodymium rare-earth magnets.
I bought some, saw the warnings and have been very careful with them. The question is whether not doing so is a case of Darwin's Law or where down the line careless people will mistake them for other kinds of material, and ingest them. Unlikely, but then people and children do stupid things with stuff they find.
