Tungsten Metal Jigs FH Katakuchi FH Shirasu These are products from nearly 10 years ago. The shape and hologram are slightly different from the current models, and they have a more shimmering appearance. They catch fish very well, so I have kept them at home. This is the only opportunity to purchase them. They are quite old, so there may be deterioration and damage to the packaging. If you are concerned about this or are a perfectionist, please refrain from purchasing.
