Hmm, a quick browse of their site shows they do have magnets, but I was thinking platic things with a magnet on thback rather than just the magnet. In particular, something big enough to not be swallowed would be good.
I used to like making fridge magnets out of magnet + something else (plastic toy, laminated picture etc). Would hot glue be strong enough to keep your kids from swallowing it?
What you want are neodymium magnets - even a tiny button sized one would be a lot more powerful than your average fridge magnet. I ordered mine from https://dangerousmagnets.co.nz/
So, one thing I want is a magnet strong enough to hold up art. But the other thing I want is to not have a kid having their intestines ripped apart (nothing gruesome in that link) if they swallow them. So I've specifically tried to avoid the rare-earth magnets, and instead want a magnet that is strong because it is big and unswallowable. Or at the very least, well attached to some larger structure.
That's a good point. I have a set of random smiley-faced magnets that came from somewhere like Para Rubber or an Asian import shop. The only problem with those is they're usually packaged so you can't test them on the shelving to see how strong they are.
You could always buy the touristy ones and get the kidlets to paint over them 😉
