Brand new, unused! For tightening knots! For connecting PE lines!! No more sore fingers! U-shaped rubber ring prevents line slippage! Wrap the line around 2 or more times and tighten! ■Details Made from duralumin used in aircraft, machine-cut, and then covered with a U-shaped rubber ring. Wrapping the line around 2 or more times and tightening prevents the line from slipping, and you can tighten it completely without hurting your fingers. Wear it on your index finger during fishing, and slide it to the fingertip when you want to use it to tighten. Or, it's small, so it won't get in the way if you put it in your pocket. Sizes are available in 3 types and 3 colors, based on the average size of adult men. (Compatible with PE line up to #1.5) By wearing the Shime Ring AL on both fingers, it is also ideal for connecting PE line and leader.
