I can answer the “let alone 100” part: they get sold as cubes of 216, 512, 1000 tiny magnet balls, or as packs of 80, 100, 200, etc. tiny magnets.
Why would anyone swallow them… the sale is restricted to 13+ or 18+ in most places, but some (including parents) are unaware of the dangers, and they go for like $2 for 100pcs.











Me. Tiny strong magnets, are good for reasonably strong attraction at short distances. Uses so far:
They should always be securely glued in place, though.
I’ve seen people use thinner ones, inside the lid of a gift box, as a latch. Also as a magnet for a LED throwie.
The problem, is stupidity like this:

Don’t let dumb kids anywhere near them! 🤦
