SemperFlash Mixes are comprised of multi-colored strands of mylar which has been crimped to give the material texture and volume. Each strand contains alternating sections in 2 to 4 different colors, depending on the mix selected. The collective effect of the material's movement in water is a kaleidoscope of those colors. This material can be used alone or in blends with solid-colored SemperFlash products, Krinkle Solid in particular. The strands are bound into a hank at one end, providing a 10-inch length of usable material - no cinching in the middle with a cable tie, which would render that part of the strand unusable. 300 strands per package.
