DetailsMany fly tiers using a variety of working threads find it economical to simply change spools rather than have a separate bobbin for each thread. These bobbin spools are identical to those included in the Norvise fly tying bobbin kit.
FEATURES:
• Precision-machined, aluminum bobbin spools • Spools hold from 50 to 500 yards of thread depending on the thread size • It's best not to overfill them.
