Tungsten Beads are approximately 50% heavier than brass beads of the same size. And they dont pose the environmental concerns of lead. The Tungsten Assortment contains 20 each of gold 1/8, 3/32 and 5/64 beads.
I purchased this assortment because the other assortment was on "back order". Turns out this one is really poor. The small beads are so small they won't fit on any hook, even one as small as a #22. They cost almost 30 cents per bead and that is outrageous considering one size doesn't even work.
