This is a strand of Green Serpentine Square Tube Beads. The strand measures about 16 inches. I purchased these beads years ago and have not used them. I'm currently de-stashing my supply cabinet as my hobby life has taken me down another path. There is no brand or artist name on the bag and they were most likely purchased at a gem show, which is where I buy most of my supplies. The penny is in the photos for size comparison. I am willing to combine shipping on all my items, just send me a message to let me know you're purchasing more than one item and I will adjust the shipping costs.
