This is a 40' coil of straightened medical grade .005" superelastic nitinol wire manufactured in the US. It has a shiny natural black oxide and performs very well as terminal tackle leader material in salt or freshwater for toothy fish.  It will stretch and recover when struck and is kink and bite resistant.  This wire should be tied using an offshore loop knot or similar ...various methods are available on YouTube.  We test both ends of the coil to verify ultimate tensile strength at our facility before shipping.  Compare it to "titanium leader wire" being sold by the large sporting goods companies at more than twice the price per foot...other weights available.  Shipped in padded mailer...free shipping to US destinations.  International buyers are responsible for all duty/Import fees.

NOTE - Picture is for reference only...it is not the actual product.
