These silk doesn't come cheap but this is the strongest and smallest tying thread on the market today.
The 30D ultra silk is amazingly strong for a small diameter and is ideal for when tying flies size 18 and smaller.
There is nothing better for the small fly addict to whip up micro dries and nymphs with.
You can still split it down further or use it to tie dubbing loops!
18/0 (30 dernier) use with ceramic bobbins.
