Tubes for tying flies.  The tube has a bulge on each end to make sure the material stays on your fly.  Use 1/4" wide tape for best results. Sold per dozen or per 100.  We also offer a larger hole in our tubes.  This hole allows a double surgeon knot in 50# fluorocarbon to pas through it.  This means you can interchange a fly from one leader to another without having to cut your leaders.  It also allows for easy storage of the flies.
