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 12-20 x 7-11mm, with a hole size of 1mm. Strand length can vary slightly from strand to strand, but is approximately 27". Great to use for your own boho jewelry designs!
