Core to the SemperFlash blends is a unique tinsel with colors that change horizontally on each single strand of tinsel. These are an amazing blend of multicolor strands of tinsel SemperFlash brings a lot to tying. Look close at SemperFlash and you will see each single strand has multiple colors built into it. That is further enhanced with the highlighter blends or background colours to offer a unique hank of tinsel in the blends where for we blend gold, silver or black for example to highlight the core tinsel even more. Think of using SemperFlash options in light day/dark day flies! When we manufactured these tinsels we did market research and found that most tinsels were tied in half, meaning lots of the tinsel in the centre was unuseable plus only half of each hank could be used for larger predator flies. As a consequence with SemperFlash Colorado Mix (BRP) you get 10" / 25cm long hanks tied at the top rather than center tied tinsels meaning that you can produce really long wings on flies for saltwater or large predators. There are 300 strands of this beautiful SemperFlash in each pack which is such great value. With full useable length of 10" strands these can be used to create flies from the smallest chironomid/buzzer breathers to huge Tarpon or Muskie flies using the full 10" length of this amazing SemperFlash winging material
