The 3D BUG WINGS are a result of spending many days on the water observing insects. There are several issues trying to replicate the profile and silhouette of a true bug. First and foremost is cast ability, Second is keeping the wings light and realistic & third is durability. I feel that these 3D wings are the best in the market in all three. I wanted them not to spin and twist as much as solid wings, and these check the box. As for realism, I feel the 3D wings are as close as it gets, and for durability, they are everything you can ask for and more. Use these Wings to emulate Cicadas, Damselflies, Dragonflies, Horse Flies, Dobson flies, and several species of Stoneflies. I guarantee they will be Game Changing in your fishing and tying! 6 pairs per package
