Oh dear!!!! I have never seen them before, til' now & gosh. I don't know. I'd say it depends on the user! You could definitely have an accidental... pinch or something, but I'd say it seems safe enough if someone is careful and truly wants to do that to themselves.

Yes! This is definitely safe to use. Ball stretching is very popular in the BDSM and leather communities.

I suggest easing into the weighted stretching if this is something super new to you. Our Ball Stretcher comes with three small detachable weights, so start off with no weight just to get used to the feeling of the parachute, then gradually work your way up by adding one weight at a time.

I would say they are safe to use as long as you the person using it, instead of the person whom it is gettin used on.
