Opaque seed beads are available in many beautiful colors, all of which actually are opaque (can not see through). These are probably the most commonly used seed bead due to the numerous vibrant colors available and their versitile application within a finished project. These size 13/o beads are strung on 12 strands gathered into "hanks", with approx. 5400 beads to a hank. The size chart above is a comparison of the various sizes we have available.
