Betts' Z-Lon is a versatile synthetic fiber for spinner wings, sparkle dun shucks, caddis emerger cases and tails. It can be used as a replacement for antron. Each package contains 20 pieces of 4" yarn.
Ok product for wing construction, comes rolled in a ball which can present challenges but overall ok.

Straightening-lon
I attach a hemostat to each end of a strand of z-lon, run it under hot water for 30 seconds and then hang it to dry and straighten. Perfect for spinner wings.

Defuses Light for Realistic Wings
Z-Lon is unique in that the center is hollow and defuses light representing the same light that passes through actual insect wings. I wish they didn’t curl yarn as it is different to straighten for larger wings.
