The difference is the action of the tie that always brings stable fishing results even under tough conditions. Aiming at the Akashi, Kada, and Naruto brand breams, which are absolutely difficult and make a big difference in fishing results, the "Sasa Lab bream mule tie series" is finally born, which embodies Yozo Sasaki's 20 years of experience. I was particular about the buoyancy of the tie and the thickness of the silicon. Verify the best thickness in 0.02mm increments from 0.2 to 0.4mm. Experience the overwhelming difference in action that has been derived through a daunting test period. To the angler who understands the real thing, Sasa Lab does not betray the fishing results.
