Refine your craftsmanship with heliotrope Czech glass rulla beads! Similar to half-tila beads, 3mm x 5mm rulla beads add depth to designs with a unique two-hole shape that's halfway between a rectangle and a cylinder. Rounded edges on these two-hole beads allow you to create a looser weave with increased mobility and freedom. Questions? Call our friendly sales staff at 1-800-366-2156, or email us.
