VIPON Tampon, the vibrating tampon.
In preliminary testing of over 100 women the Vipon has been proven effective for the relief of menstrual pain with NO side effects, just a soothing sensation.I didn't know whether to put this into Neat Stuff, Laughter, or Errant Ramblings. If it works as advertised, then it's the former. If it doesn't, then it's the middle. And the latter was the only other possibility with my category choices.
And apologies to the men who get squicked by this.
