Textreme Holographic Fibers 0.37 mm is a thin, luminous mounting material made of laser-treated holographic flat film for intense, attractive reflections. At 0.37 mm (1/69") wide, it's the thinnest version in the range, ideal for delicate ribbing, perdigone bodies and small nymphs, where precision and discretion are essential. It combines perfectly with other sparkling fibers such as Crystalflash, Glossy Flash or Crimpy Flash, as well as with natural materials such as marabou, especially for enriching streamer tails. Also available on spools, it is packaged in 300-strand packs, offering fitters a durable, versatile and essential material to give their imitations sparkle and appeal.
