These are Talon Rattle Eyes

You can call them Rattle, Jiggle or Dolls Eyes, its all the same to the fish.

The black center moves around and bangs against the clear outer shell and in doing so produces a rattle, so we call them Rattle Eyes.

This banging around usually attracts predatory fish to you, err, to your fly.

Great addition when added to Bunker flies, Blues/Tailor, Squid, Sea Habit style Streamers, Deceivers, Offshore flies and Trout Streamer types.

Simply apply epoxy glue or super glue and your eyes are fixed in place.
