Choose a captive bead ring that corresponds with the size of your piercing. Sizes range from 0 gauge all the way to 20 gauge. The smaller the number of the gauge means the larger the piercing.
Pry open the bead ring with your fingers, making sure to pry only enough to allow the captive bead to slide out between the points of the ring.
Place the bead in a small box to keep it from rolling away. A compact makeup mirror also works well to hold the bead temporarily.
Grasp the area surrounding your body piercing with your thumb and forefinger. Allow the piercing holes to line up as you squeeze your skin together.
Insert one of the pointed ends of the ring through one of the piercing holes. Slide the ring through carefully until the pointed end protrudes from the other piercing hole.
Grasp the bead firmly between your thumb and forefinger. Rotate the bead in your fingers until the holes match the position of the points of the ring inserted in your piercing.
Wedge the bead between the two ring points and allow the bead to slide down one of the points.
Keep a steady hand and gently squeeze the ring with your thumb and forefinger until the other point of the ring snaps into the bead's hole.
