A frequently used material for making shellbacks of the ever-popular Czech nymph, caseless caddis larva, caddis pupa, backswimmers, worms type patterns, shrimp, scuds, and other nymph bodies. These strips are exciting in that they are shiny on one side and dull on the other. The material is very strong, and stretchy so it makes an excellent halfback material. A popular material used in fly tying.
