This is a Paragrab 5-inch trailer assembly, a limited edition release from Issei in the past. It was a short-run item, making it a very rare worm. It is now discontinued. Issei enthusiasts may be looking for this. By the way, it caught a lot of fish in Lake Biwa. Thank you. *The package has been disposed of, so it will be shipped in a different Issei worm bag.
