These pre-cut tails can be used for almost any style of baitfish fly pattern or surface popper and produce a frisky, fish-attracting tail action. They have a realistic baitfish profile offering fly fishermen a simple and effective alternative to using hackle and other traditional tail materials. They are made of an almost indestructible synthetic suede that cannot be bitten off, will not shrink and is easily colored with a permanent marker pen. 6 per package.
