These beads, the rondell or abacus shape,
are on 15 - 16 inch strands, temporarily strung, usually on monofilament (plastic fishline).
The holes are relatively small, probably less than 1mm. You won't be putting leather through them.

Combine all the individual strands (mixes not included)
listed in the SEMI-PRECIOUS BEADS category to get the pricebreaks.
