This is a great set for fly fishing, including a variety of fly materials, hooks, and threads. - Fly Material Types: Includes a variety of fly materials. * Stored with desiccant for good preservation. - Comes with an organized storage case. - Color Variations: Multiple colors of fly materials. - Hook Types: Includes various hooks. My father received this upon his retirement. I am a lure fisherman and don't use these, so I'm selling the set. I have no knowledge of flies, so please judge based on the images provided. No returns or exchanges after the sale. I prefer Eco-Mercari delivery if the destination is within the eligible area.
