Slinky Fibre is basic material for many saltwater flies. Slinky Fibre has thin fibres, which are still very durable. So your flies will last ages in use. Fibres are about 20 or 30 cm long and you can create big fish imitations.
Slinky Fibre can be used as a tail or body/wing material. When making big bodies/wings, it is recommended to tie only small amount of Slinky Fibre at a time to the hook. This will result better movement and profile for the fly.
