Semperfli Nano Silk 1 5 5 1

An amazing thread, extremely strong and fine it gives confidence to fly tyers and avoids build up.  MUST be used with ceramic bobbin holders.

Sizes Available: 18/0 (30 Denier) & 12/0 (50 Denier), 100m spools

Colours Available: Black, White, Red, Olive, Brown and Orange

Nano Silk Ultra 30 Denier:  Just 30 denier or 18/0 this thread is ideal for tying the smallest of flies, from sizes 18 to 32! It is Ultra Fine and Ultra Strong.  For the smallest flies you can split Nano Silk Ultra to form dubbing loops and still avoid build up but still tie with little thread of fly breakage.

Nano SIlk Ultra 50 Denier: 50 denier or 12/0 is the traditional silk in the range. Super strong, this thread is virtually unbreakable and the choice of a great deal of anglers worldwide.  Even though it is a fine thread, you can rely on it's strength and even split it further if you wish!

I bought the 18/0 in error but then proceeded to tie a number of traditional Irish wets, bumbles, winged etc, which I always had bother with head bulk.

I bought the 18/0 in error but then proceeded to tie a number of traditional Irish wets, bumbles, winged etc, which I always had bother with head bulk. Not this time, almost impossible to bulk it up. Very fine and strong thread and will be buying 12/0.
