This is a gang rig for fish like the thread-sail filefish (Kawahagi). Place bait such as krill or cut bait in the cage. When the fish nibble, you'll feel a bite, so quickly jerk the rod upwards to hook them. You can catch not only thread-sail filefish, but also horse mackerel, mackerel, sea bream, and other fish. It can be folded compactly for easy transport. Please refer to the images for the size. If you need multiple items, please let me know how many you would like. We offer a discount for multiple purchases. We also have other affordable fishing items available. Thank you. #FishingTackleForSale
