Reliable Quality: The swivels are made of copper body and stainless-steel rings, and the ball bearings have been tested to be strong. With maximum security, the swivel can endure the any fishing environment, so you don't have to worry about rigs breaking or losing fish. Flexible Rotation: Ball Bearing 3-Way Swivels help keep line twist to a minimum when making deep drop rigs or any rig where line twist may be a concern. The inner stainless steel ball bearings rotate smoothly, driving the entire swivel to rotate quickly, which will make the fishing lures appear more natural and attractive in the water. Helps avoid line breakage and twisting to ensure a great presentation. Smooth Surface: The surface has been electroplated and oxidized, which keeps it from rusting and going bad. The coating also helps with abrasions on the line. Approved for use in saltwater, high-speed trolling, jigging, and offshore fishing. Multiple Usage: The 3-Way fishing swivel is convenient for you to make your own rig; you can use it to make any heavy-duty rig or deep-sea rig for freshwater or saltwater fishing. It also is popular for fishing with live bait and trolling with artificial lures.
