Perfect for black porgy (kurodai) fishing. 10 pieces for 1340 yen. Can be used for hechi, ochi-komi, and boat spinning. Ideal when you run out of live bait or for those who don't want to handle live bait. Keep them in your tackle box and they'll come in handy. This type is used by piercing a hook through the shell. The inside of the shell is made of silicone, making it easy to insert the hook. The shell size is approximately 2cm to 2.5cm. Since it's a no-sinker, use your preferred hook and weight.
