Materials for tying flies and fly tying tools are constantly evolving, so it is difficult to keep all types of fly tying materials. We at "4Trouts" are constantly working to find fly tying materials tools that are new and hot in order to be able to offer something for almost all fly tyers. We have chosen to focus our fly tying on, above all, sea trout and pike fly tying, fly tying material for dry flies, nymphs and salmon flies.
