Holds moistened cotton ball. The cotton ball is dipped in water so that it becomes moist, without dripping. When moisture is needed, the point can be moistened by wiping the pad of the little finger across the cotton ball and then across the point. Or, you may lightly touch the bottom surface of the moxa punk to the cotton ball and then place it on the point. Moxa rings are used to make the application of direct forms of moxa smooth and easy.
