Fly Box Crystal Hackle has been developed specifically with just one side of material allowing the core to lay flat on the hook, pushing the synthetic fibres out. Cut to 10mm in length, Crystal hackle can be wound on to almost any fly but excels when being used as a substitute to a hackle. Ideal for tying a range of wet flies such as dabblers right through to bodies of lures or boobies. This material is professionally dyed using state of the art pressure dying machines, fully computer controlled to ensure 100% colour consistency & intensity through the full range of Fly Box Products!
