This is unique stuff. Dyed over white herl. The herl is actually white and over dyed. The colors are bright. These would make some interesting nymphs and collars on flies. I thinking about Chartreuse Prince or great looking collars for Frenchie Jigs. For all you soft hackle addicts, this could brighten up some boring, dull stuff. Like a red collar below a partridge and orange for example. The Black is over dyed natural so it is metallic black peacock.
