We put together this bait kit to make microfishing easier for you. It includes a bottle of Marukyu microfishing bait and a Marufuji microfishing bait pump. Both are specially made for microfishing.This stuff is really easy to use when you want to bait tiny microfishing hooks. You put the bait into the pump. Then you push down the plunger on the pump and a small amount of bait comes out of the tip. You basically just "squirt" the bait right onto your tiny micro hook. And all species of micro fish seem to love it.
