Price listed is for one ounce of acrylic beads. These are mixed black acrylic beads that range in size from about 4mm to 17mm. The holes of these beads measure approximately 1.06mm but sizing may vary from bead to bead. Since they range in size I cannot guarantee the number of pieces you will receive only the weight. The sample ounce I pulled had about 40 pieces. These are a little dusty and need to be wiped clean.
