This biodegradable foam has more benefits beyond keeping our waterways cleaner; in boasting a design much improved from the original plastic design in every way possible, anglers will notice better strike detection, no more leaks or cracks, supports 25% more weight on the water, and more. Indicators that end up floating away for any reason will break down over a long period of time. They will not dissolve or be compromised in any way during normal use. Sold 3 to a pack.
