Special tying thread made of high tenacity twisted filament, great tensile strength compared to its size. Thread suggested for tying any artificial. Thanks to its twisted structure with two ends, it is easy to make dubbing loop, once opened the return to its original twisted position is virtually automatic, without the aid of a twister. Version 8/0 is particularly suitable for the tying of thin bodies and for head closures, suggested for hooks from #14 to #24. Version 6/0 is recommended for hooks from #8 to #18.
