Wayne Cooper Flex Eyes are a popular selection for fish eyes. The eyes feature a black pupil with gold ring and are painted a lighter color to enhance expression. The eyes are non-breakable and are priced for commercial use. Tips for measuring flex eyes: Measure eye socket after fish is skinned; the iris is the same size as our glass eyes; the overall flex eye is larger than the eye socket; the sclera band will not show all the way around.
