These tungsten bead head kebari sinks fast and is a great option to bring your fly down to the fish hugging the bottom. This fly pattern comes from a fly I have seen Tom Davis mentions he uses in the article "The Marvelous Bead Head Futsu Kebari" and I have found it to be a good producer in deeper runs or during non-feeding times of the day.
Tied on a high quality size #12 Short Shank Moonlit hook.
You get 12 flies.
Casting bead head flies on a tenkara setup needs to be done right as they can damage your rod if it hits your rod, see the article "Safely Casting Beadhead Flies on Tenkara Rods" for instructions if needed.
