The Ridge Sbirolino Slow Sinking from TROUTMASTER is a slow sinking Sbirolino with a slim shape in various casting weights. Due to the transparent material, it is barely visible underwater. Due to its slim shape, this sbirolino makes only a slight dip in the water, so that the fish hardly notices anything. Our unique Sbirolinos have 2 edges on each side so that they do not spin and walk stably through the water. The pure white color is easy to follow and gives better visibility of bites. Especially for fishing just below the surface.
