Dr. Slick's Titanium Insert Fly Tying Bobbin is a premium fly tying bobbin that will be an important part of your fly tying tool inventory. With titanium oxide inserts it is even smoother to use than ceramic. The inserts have a raised textured finish on the inside of the bobbin to reduce friction of your fly tying thread. It works just like a textured fly line does. These fly tying bobbins are insanely slick. These are super high-quality fly tying bobbins available at an economical price.
3 sizes available: 3", 4", 4.75".
