13 Fishing Mini Quatro Superior Soft Plastics feature pyramidal appendages that transfer vibrations and create life-like movements to trigger more strikes. These baits are 10 times tougher and last longer than the competition. Designed for ice fishing, the plastics are infused with 13 Fishing's "Donkey Sauce," a proprietary formulation of amino acids and proteins that stimulate feeding and aggression in predatory game fish.
