[GIKR Grooikra 25mm*1g]
For topwater use, shake finely to spread ripples or add a slightly stronger rod action to create a pop.
It is not the sound of pushing it with a cup like a popper, but the sound of a spherical object is drawn into the water, so you can hear a sound close to the watering of a pellet.
When retrieved, it can be used as a crankbait, and swim in the water. This swimming leaves a wave, and is highly appealing to fish during the time of aquatic insects to feather.
