They are steel balls... Not much to say other than they work well with spacerail.

We have a fairly new version of Mouse Trap and these worked to replace the one we were missing. They are not exactly the same size as the original one, but they are heavy enough to trigger the next event.

These balls rust pretty easy. Description says they are "high quality chrome steel" and I would disagree with that statement but other than that, they are decent.
