There are little ceramic beads in a jar. Their surface texture carries the powdered lube. You get a jar of the straight powder to charge/recharge the beads.

The beads look darker than in the pic when I consider them sufficiently charged. You don't have to load a bunch of the powder in there, but you'll need to give the beads a good bit of shaking to get the initial coating to take.
