The guys at Recon Towers love these awesome Magnetic Ball Stretchers. They clip on and off using a strong magnet, which avoids the need for screws and allen keys.
Made from smooth stainless steel and in a variety of sizes and weights. We recommend the larger width if you have a bigger ball sack!
Note: Please avoid solvents or water use only alcohol to clean magnet area.
