Because it comes in 8 colors (those showing, plus clear), this wire can be part of the design, blending with your beads.
This is a 30 foot roll, .019" diameter (about 1/2 mm), fine enough for seed beads, pearls, and other very small holes. It can be threaded through beads without needles, just like tigertail. But, unlike tigertail, it is very flexible, and drapes smoothly.

You won't be disappointed in this product! Tigertail is the traditional beading wire for strength, and is less expensive, but this wire is stronger, much more flexible, and comes in 8 colors. We use it for our best necklaces and give it our personal recommendation.
