are you reffering to what type of material is used for the lines, of what the actual lines do on a 1:1?
for the first line, (on the left) it is chrome type elastic, avaliable from spotlight, with the elastic removed, and replaced with wire. and i have a feeling the one at the front is the same stuff, its just how the light is reflecting. also if you stretch it out, it slightly changes the braid pattern, this may be what has been done with the front one. hope this helps
