Description

UNI Big Fly Thread 400 Denier is designed specifically for big saltwater flies, bass bugs and other tying applications where a very strong, easily-handled thread is necessary.

• 80 yard spools available in all the right colors
• 400 Denier
• Untwists quickly and easily for flat-thread applications
• 4 times stronger than a 6/0 thread and four times bigger too
• Same material (polyester) as UNI 6/0 and 8/0 thread so it won’t dull fly-tying scissors
