They call these Evil-eye beads to wear or use or hang about to ward off the dangers of others.... :) You could use them just as bead dots in a mosaic, or turn them in another direction and have two eyes for a bug or animal, or if you are superstitious ... use them to your benefit.
Lampwork Glass Evil Eye round handmade beads- so they are all slightly different, 10mm diameter.
Sold in a bag of 23 for $5.25
