The danger with small magnets like this is that, just like you did in this comment, people simply don't understand that they're more dangerous than other "small pieces of matter" no matter how many warnings the companies put on the packaging. Most other small items, even fairly sharp ones, generally pass through the digestive system without incident, but magnets stick together and trap intestinal tissue causing tissue necrosis and death within days without surgery. Lest you think I'm singling you out somehow, every discussion I've seen on this issue has unintentionally demonstrated the complete ineffectiveness of the labelling.
