NISSIN ONI Ryu Tenkara Level Line
Designed by Masami “Tenkara-no-Oni” Sakakibara. It is a Hi-viz Orange color quality level line on a 20 meter spool.
If you don't know what size to get, get the #3.5 level line. #3.5 is the most common size used. If you have a really stiff rod go with the size #4 as it will cast better with stiffer rods.
