Thank you for viewing. This is a set of 4 colors of CANAL HAIRY WORM fly tying material. This material is made by trimming rabbit skin hair short and cutting it into strips, similar to Trout Gum, but with a few millimeters of hair growing on the leather. It can be used for fishing in managed fishing areas, rivers, and the sea, and is especially highly regarded in managed fishing areas. ● FL ORANGE ● GINGER ● YELLOW ● CHATREUSE To avoid confusion after opening, the color names are written on the bags, but the items are unopened. After purchase, they have been stored in a container box indoors, so I haven't noticed any significant quality deterioration, but please understand that these are used items stored by a private individual, and refrain from purchasing if you are overly concerned about condition.
