Fly Materials Stripped Goose Biot Set of 3 ① Green - BROOK ② White (Manufacturer Unknown) ③ Mixed (Manufacturer Unknown) These are made by stripping the short fibers from goose quill. Please check the colors and number of pieces in the images. Because the original color remains even when wet, it is ideal for accurate imitations of specific insects. They are hard and pointed, and can also be used as nymph antennae and tail/leg material. When wrapped on a body, they can reproduce the segmented patterns of aquatic insects. Using them with fine, natural, dubbing spinners, and colors will create a very realistic fly (quoted from the internet). Since they are hard as they are, soaking them in water before wrapping will make them easier to work with. Thank you.
