Having the tungsten metal weight on the outside lip allows for more room for the lure to make a rattling vibration. The TN/50 was designed for small bodies of water like farm ponds, but it works great virtually anywhere.  This model is smaller than the entry level US Models.  They are also Exclusive Japanese Colors.    Jackall’s specially designed weighted system makes it possible for the lure to stand straight up at the bottom. This will create less snagging than traditional types of lipless crankbaits.
