Made of highly conductive rubber, flexible and easy to use and clean properly. These are the hollow version vs the solid Sparklers. High-quality stainless steel tips at the bases are safe and smooth and spread the sensation wonderfully.  Standard 4mm banana connections are at the top for connecting electrically.

These are available in 6mm and 8mm diameters, with short and long versions of varying lengths approximately 6.5 inches for short and 9 inches for long.

A very versatile electrode, they are primarily used for urethral stimulation, giving a highly concentrated and intense prostate sensation.  They can also be wrapped around just behind the penile head, or just laid against the penile surface up and down (held in place by a non-lubricated condom for example).  They can also be looped on themselves for vaginal or anal insertion. These are a unipolar electrode and can be paired with any other unipolar electrode or included in a triphase configuration for an almost endless variety of fun sensations.
