Hareline UTC Wire comes in a wide range of colors and sizes. The most common uses are ribbing material and bodies. UTC Wire is great for adding color and shine to your flies as well as some additional weight to get them down quickly.
I use this wire in all of the different sizes and many colors. It is plenty strong even at the small sizes to keep flies together. I like the color selection to add to many different flies as well. Would recommend for any tying.
