Description Vanish Fluorocarbon Fishing Line 250 Yards is virtually invisible and proven not to spook fish! Designed to refract light just like water, Berkley's Vanish Fluorocarbon Fishing Line "disappears" in the water. Vanish Fluorocarbon also maintains its strength when wet (unlike other lines), casts well, and is sensitive enough to detect the softest bites. Plus, Vanish offers excellent shock absorbency when you set the hook. Refracts light like water Virtually invisible to fish Shock absorbent Maintains strength when wet
