Exactly what I needed
I need magnetic balls or pills to use with my ink to stir when on my string machine. These fit the bill

Great for tiny chemistry.
I was a bit skeptical because these seemed really cheap but after a bit of testing, they do indeed stir and are coated with PTFE. They are great for very small reactions. They don't do as well as longer stirbars do when the vial is not centered on the stirplate. If you're going to be setting up several reactions on one stirplate, these might not be the best.

Don't
Magnet bars are so weak there's no mixing, extremely weak and little movement is slow. It is a great idea but I cannot use a single one. Not 1.
