Magnetic ball stretcher (stainless steel·3 weights·35mm inner diameter)

A stainless steel ring that passes over the scrotum and closes with magnets. Rather than screwing shut, two pieces hold together by magnetic force, so it goes on and comes off quickly. The supplier presents it as a way of stretching the scrotum over time.

It closes with magnets, not screws

Ordinary ball stretchers need a hex screw turned several times, but this one closes when you bring the magnet faces together. Taking it off is a matter of sliding it sideways, so no tool is needed. In exchange, the magnetic force is strong and it snaps shut suddenly, so you have to check first that no skin is caught between the faces.

Three weights and a 35mm inner diameter

The inner diameter is 35mm on all three, and only the height and the weight differ. 35 x 30mm weighs 448g, 35 x 40mm weighs 560g, and 35 x 60mm weighs 833g. The greater the height, the stronger the downward pull, so if this is your first time it is safer to start with 448g. The set is one ring.

The order for putting it on

The supplier advises pulling the scrotum down and away from the body, passing it through the opening of the ring, and checking that all the skin is behind the ring before closing the magnets. Skip that order and the magnets pinch skin as they close. The supplier notes that the stated measurements may vary slightly.

Before you use it

The weight is the whole point of this item and its danger at the same time. Even 448g pulls downward without letting up, so it does not suit walking or climbing stairs. The magnets are strong, so it must not be kept near cards or electronics, and anyone with an implanted pacemaker should not use it at all. Keep the wearing time short, and if numbness or a change in color appears, take it off immediately regardless of how long it has been on.
