> ZenMagnets has always put warnings on their products

I'll have to dig up my old set of magnets but I don't believe their early warnings would clue you in to exactly how dangerous the magnets are when ingested. The newer warnings are considerably more effective, I suspect, if what is on the website ("MAY CAUSE FATAL INTESTINAL PINCHING") is representative of what's on the package.

edit: I hope this stupid warning is not a real thing today: https://images1.westword.com/imager/one-of-the-warning-label...
