Overview
A small biodegradable fly-fishing strike indicator weighing about 4.54 grams, sold in assorted colors. Built to break down over time rather than persist like standard foam or hard plastic floats.
The biodegradable material targets fly anglers who want a lower-impact option if the indicator is lost on the water. At 4.54 grams it's featherweight, sized for delicate fly presentations rather than heavier bait rigs.

Performance notes
