Works with 5x3mm (diameter x height) neodymium magnets.
Note that thinner plastic curtains are likely to rip a little when snapping on or removing the gripper, so be careful and don't use it on an expensive curtain that means a lot to you.
I use these snap-ons on a cheap 5€ IKEA curtain, so I don't care about a tiny rip here and there.
