A balance that can be built into the arm section. The cushion rubber is built into the arm to reduce the distance from the rigg. Shima mashii is a fish that will penetrate into the top of the box (it is so much to catch the bishi), so when the rigging is close to the bishi it will improve the hitting rate. Cushion rubber is an essential item for those who have weak mouth circumference, so this balance is specifically designed for shimmering fishing.
