You can split it down further or use it to tie dubbing loops, giving you flexible options for detailed bodies or stealth profiles. Recommended you use with a ceramic bobbin for consistent tension and smooth feeding. Length 100m spool, ready for extended tying sessions and repeatable color from marker customization.
