Beadalon 7 is exclusive to Beadalon (made in USA). It is softer than tiger tail, and more supple, for a smoother drape. Craft-series Beadalon 7 encases 7 strands of fine-diameter stainless steel wire within a kink-resistant nylon coating. It is also strong and more flexible than tiger tail, and is abrasion-resistant for longer-lasting results. Beadalon 7 is easy to work with (no needle necessary), super-strong and renders secure jewellery that lasts. Use Beadalon 7 for most general beading designs. You'll find Beadalon 7 has become a favourite among professional designers and craftspeople.
This listing is for .30mm (.012") with a 5kg (12lb) break strength, in 'bright' colour which is the shiny dark silver colour (more like nickel) and comes on a reel with a plastic holder which snaps back in place to keep your wire from unraveling from the reel.
