Semperfli Waxed Thread

The old classic – lightly waxed thread. Very similar to the old-time favourite UNI, these waxed threads are an amazing value for money with spools being packed with 220 meters or 240 yards of thread. A spool like that will definitely last anyone a long time.
The 18/0 is 30den thick and is best suited for very small flies, size 18 and under
The 12/0 is 70den thick and is the best all around option for trout and grayling flies sized 8-18
