This Rio Fathom CleanSweep Slow Wf6S2/S4/I is Brand New, just comes without a box. 

Sweep style sinking lines designed to cover a multitude of depths while lake fishing Rio's Cleansweep fly lines are built with a clear intermediate front end, seamlessly attached to a faster sinking body section and then to a slower sinking running line. This blend of sink rates results in a deadly fly path through the water, with the line “sweeping” the depths during a retrieve; from the surface, to deep, and back to the surface again thus covering a multitude of depths with each cast. Each line has a short, quick-loading head for minimizing the number of false casts, and a Hang Marker that shows anglers when to stop stripping.
