Kreinik Flash In A Tube™ is a synthetic metallic material for adding sparkle and light reflection to the tails and wings of many flies. Kreinik Flash is unaffected by saltwater or epoxy finishes, yet is flexible enough to be mixed with marabou, enhancing its action in the water.

It is the one and only flash to use on the Kreelex Fly. Add strands to the tails of woolly buggers, bass bugs, poppers, eels, and leech patterns. Mix with bucktail in streamers. Single strands can be used as ribbing on nymphs and wet flies. Perfect in popular dry fly patterns. The white glow-in-the-dark can be used as a substitute for calftail in a Royal Trude, or as the wing post in a Parachute Adams. It’s like having a built-in strike indicator.
