These seed beads are made from brass with a color coating. Great for a variety of bead weaving and loom projects. The edges of the holes may be slightly sharp, due to the manufacturing process. We recommend using a stronger beading thread such as Fireline, Wildfire, or Powerpro. KO or Nymo threads are not recommended.
Measurements: 11/0 Size (approximately 2.1mm in diameter and 1.5mm along the string hole). The holes will accommodate wire or thread up to 1mm thick.
