Focals come in many sizes, shapes & colors. While it's not necessarily the case, as the name implies, the Focal Bead is intended to be the center of attention in whatever it's used in.
Many of my beads are shown on "wires". This is due to the fact that I do live shows, and the beads are wired onto display cards. I take cards off for photos, but leave the wires on. Focal beads will not be shipped with wire unless they are carded for display.
