6/0 UNI Thread
UNI 6/0 is much bigger than its name implies. 135 denier
This is a great thread for larger patterns and streamers. Good for Crazy Charlies and San Juan Worms! 6/0 UNi is 135 denier, meaning it's about twice as big as 8/0 Uni or 6/0 Danville or 70 D UTC....bigger thread, bigger flies.
