The standard for clouser minnows! Of course the thin emamel painted eyes will rapidly chip since these flys are normally bounced over bottom cover/rocks etc., but this can be minimized with a thin overcoat of epoxy or quality clear nail polish.
Purchased the sm, med, and lg in the gold black color as a starter set. These add a touch of realism and most important weight with out adding split shot, etc. to the line. Easy enough to change colors with a dab of paint or order other colors as needs dictate. Good product if you are tying weighted flys with buggy eyes.
