Hareline Stonfo Tapered 5-Size Pin Set for Tube Fly

The Stonfo Tapered 5-Size Pin Set for Tube Fly is a precision tool for tube fly tying that keeps tubes securely locked while you build flies. These finely machined stainless steel tapered pins accept internal tube diameters from 0.6 mm to 4.0 mm, delivering reliable, repeatable results for a wide range of tube sizes. Each set contains five sizes to cover common tube diameters used in nymphs, emergers, and streamers.
