Whether they are nymphs, wets nymphs or dry flies, with this product you can tie the tails of your artificial flies. Simply cut a tuft of hair of the desired length and quantity and tie it to the hook with the tying thread. Various colours are available as well as the "barred" variant, which is very interesting.
Very often adding the tail to your artificial fly can make a difference, making your imitation very truthful and captivating, while in some dry fly dressing the tail is meant to balance the fly when using it in particularly calm waters. All fly tying materials are of excellent quality and come from the hotfly company.
