I purchased one strand of these 3mm rondelles, and it came to be a total of 173 beads. They are very flashy silver, and don't appear particularly black at all on the strand, but do when grouped in a pile.
They are incredibly consistent. Size, color, shape is very similar bead to bead. There is some variation in color of flash- some are more flashy than others- and a few are imperfect in shape, but across the board (especially at a glance) they are very near perfect.
Photo is taken in low-medium natural light. Photo was edited to slightly increase brightness, to allow definition between beads. Beads appear generally more grey in person, even while grouped.
