EVA Foam Spools are lightweight, convenient, and an inexpensive way to keep your tenkara fly lines neat and ready to go. Never waste time searching for a certain line or getting tangles. For real efficiency, tie your flies on at home – where there’s no glare or wind and maybe even a magnifying glass, then simply attach your line to your tenkara rod when you hit the water - happy fishing!
