Semperfli Nano Silk Ultra 30D 18/0 Black

Great company to deal with. Selling a great variety of products. The nano thread is just what I needed. I will certainly be using this company in the future.

Very strong silk without the bulk. Will be stocking up with other colours.

I usually tie with spiderweb and with its associated issues I have been looking for a thread with the same invisible qualities but with greater strength. Having tried several GSP threads I believe that the Semperfli 18/0 Nano silk is the best I have tried albeit the colours are "fast" so bleach out. To overcome this issue, buy the white thread and colour with permanent marker on the last few inches prior to the whip finish

A very fine, strong thread for tying small flies.

I thought it was hype about this silk, but I've tied my best flies ever with this product. Thin but very strong. Highly recommend.
