Nano Silk Pro 20D Black

Semperfli Nano Silk Pro 20D Black

Great for Trico and Micro flies for e.g. sizes 18 to 32 !
Possibly the world's strongest fly tying silk because of its diameter.

The Nano Silk Ultra is ideal for flies from size 18 and smaller. And you can split it even further or use it to tie dubbing loops.

At only 20D, this has a breaking strength of 750 grams this will stay flat and disappear, but still has incredible strength for tying micro flies.
