Hareline CHERNOBYL After Glow FIBERS - GLOW-IN-THE-DARK Wing Material
Does not absorb water, making it easy to cast.
Add a little or a lot to make your flies glow.
Remember, unless it's clear, deep water is dark in the daytime.
Glow-in-the-dark materials can be recharged by the sun on each cast.
Also good for ice-fishing.
