Semperfli Mylar Cord (1.6mm)
For the ease Semperfli have already removed the inner cord so that you can get straight on with tying without having to do anything fiddley. The Mylar pipe gives a stunning fish scale effect for Salmon, Trout and Saltwater flies.
With the crisscross structure of the Mylar strands in the manufacturing process this provides a glitter effect and when used as a body provides staggering attractive properties to predators.
Also you can tease the piping end loose and use as a tail.
