I used imported glass Czech beads and Japanese Miyuki Delica glass beads. A one of a kind artisan design. Weighing at 0.1 oz so they are very lightweight.  The ear wire is 304 Surgical Steel which is a specific type of stainless steel and is hypoallergenic.  Real colors may slightly differ from monitor to another, as it depends of different monitor settings.  If you have any additional questions about them, please contact me! I did not use any nylon to make this product, only polyester thread.
