This is a metal vibration lure for saltwater fishing that appeals with a trembling action. It has a specification that allows you to change the action by using the front hole for fast retrieves and the back hole for slow retrieves. We have made it a set of 7 colors so that you can change the color depending on the weather, water turbidity, and fish's reaction. This is a very cost-effective set. We also have 10g, 14g, and 21g available, so please take a look if you'd like. *Please note that this is not Valley Hill's Jado Reon.
