My Clousers are tied on Mustad 34007 stainless steel hook. Sizes #2 and 1/0. Length of 1/0 is over 3” long and #2 is up to 2 ½ in long. Dumbbell eyes are chrome plated lead with prismatic eyes, the head and body is coated with 2-ton epoxy for a hard, clear, durable finish. The Clouser Minnows are one of the most productive flies ever developed. Fish just “love ‘em.” Originally designed by Bob Clouser.
