In the free roll, it swims lustrously with moderate shimmer and produces small crustaceans and small fish, which are the staple foods of gobies. Since it falls slowly in a horizontal position, it gives a bite chance to gobies who cannot catch up with the crankbait. Range control is easier than crankbait, and you can freely capture any range. Its compact size allows it to be used like a worm. Pink needles with Keimura paint are used for the hooks. It emits pale light in response to ultraviolet rays and strongly appeals to gobies.
