UNI Glo Fluor & Phospho High-visibility thread for glowing fly accents.

UNI Glo Fluor & Phospho is a specialty fly-tying thread designed to add bold, glowing highlights to your patterns. With its fluorescent and phosphorescent properties, this material makes flies stand out in low-light conditions, deep water, or murky streams, attracting fish when visibility is low. Perfect for hot spots, tags, ribs, or subtle accents, it enhances both nymphs and streamers with a burst of visibility. Durable and easy to work with, this thread lays flat and wraps smoothly, giving tiers professional-quality results every time. Available in multiple colours, UNI Glo Fluor & Phospho is a powerful tool for tying flies that demand attention.
