These EVA line wheels are great for storing your line or pre-rigging it ready to go so all you have to do is unwind the line and connect it to your pole. Because the wheel is made of EVA foam you can hook your fly anywhere on the wheel to hold it snug in place.
The wheels are 7cm wide (about 2.755 inches) and 1.5cm thick (about 0.6 inches) making them perfect for furled and level lines. The middle hole is large enough to fit snug at the upper end of the cork handle of your Tenkara rod. The groove is deep enough to even fit the longest furled lines with ease (such as a 28 foot Nodachi line from Moonlit Fly Fishing).
I like to use a permanent marker write on the side of the line holder what type of line it is and the length, since I use several different types of furled lines at different lengths.
