Soft Flex Wire is the designer's choice in bead stringing wire. Soft Flex Wire is a lead-free beading wire for designers that demand strength and durability. Soft Flex Wire is a superior beading wire, created by beaders for beaders. Soft Flex Wire is constructed of either 21 or 49 micro woven stainless steel wires. It is supple enough that it can be knotted and comes in a wide variety of colors. It is available in 3 diameters: .014, .019, and .024. We recommend Soft Flex Wire for designers that want their pieces to last and eliminate the frustration of restringing. Basic Usage: .010 Very Fine - Ideal for embellishing, weaving, crocheting and stringing very small beads. We suggest finishing with 1x1mm crimps. .014 Fine - Ideal for soft materials, seed beads and fresh water pearls. We suggest finishing with 2x2mm crimps. .019 Medium - Ideal all purpose wire. Great with glass, mineral, and metal beads. We suggest finishing with 2x2mm crimps. .024 Heavy - Ideal for abrasive materials, large stones, lamp work and bracelets.

They are perfect for containing your beads for each project. Or, tear off the label and toss your unwanted spools in a recycle bin. All stainless steel used in the construction of Soft Flex products is 100% recyclable. Our nylon coating is derived from renewable resources and can be recycled. Think green!
