Tired of fiddling with that hex key to get your metal ball stretcher on and off, no more hex key to worry about. These weights use magnets to close. The rounded edges and the smooth steel feel great against your skin.

They clip on and off using a strong magnet, which avoids the need for screws and allen keys.

Powerful magnets lock this stretcher on and keep it nice and secure. You will definitely feel the tug as you walk around.
