Our main product, the worm, cannot be used on its own; it only functions as a fishing tool by combining it with hooks, sinkers, etc. to create a "rig." We want to create a terminal tackle that is acceptable for using our own worms. The first product that embodies this idea is the ``Tungsten Drop Shot Slim Weight.'' As the name suggests, this is a sinker exclusively used for drop shot rigs (down shot rigs), which are often used in modern worm games regardless of the season or location.
