These beads are made entirely of metal, starting out with a brass base, and then the various highly durable finishes are added. They are very uniform in size and are a much more rounded bead compared to the Japanese glass beads which are generally more cylinder shaped.
Due to their shape they can be especially handy for projects that require the beads to snug up against each other, for a close fit.
These seed beads are a definite advantage in many designs. They are available in 7 different metal finishes, in three sizes.
Try them! You will be glad you did!
