These rustic beads are said to be made using recycled camel bone. Each bead is hand-carved into its initial shape. Some are then patterned through additional carving on the surface of the bead. Each bead measures approximately 4-5 x 6-8mm, with a hole size of 1mm. Strand length can vary slightly from strand to strand, but is approximately 30". Great to use for your own boho jewelry designs!
