The processes used to make Czech 3-cuts give these beads more rounded edges than 2-cuts and several random facets per bead. Each bead is uniquely shaped, so 3-cuts are not recommended for projects requiring strict uniformity. Size 12/0 3-cuts measure approximately 1.9mm. These transparent beads allow light to shine through, while luster finish gives them an extra shine. Sold by the hank; hanks contain approximately 3000 beads strung on 10 strands. Made in Czech Republic.
