Line winder with a spring mechanism for easy line winding. Used for replacing PE line on two spinning reels. I'm selling it because I haven't used it in a while. I used to have trouble with line twisting, but this ingenious product winds the line straight and is comfortable to use. Image 15 shows the line after winding, neatly and without slack. The line is Seaguar PEX8 1.2, reel Shimano 2000. - Product Name: Super Line Markey - Color: Black, carbon body - Spring Mechanism: Yes - Application: Line winder Thank you for looking.
