Theros® Massive Balls are the only vaginal balls or anal balls worldwide made from solid, antiallergenic implant-grade stainless steel AISI 316L. Like Viball®, they release no toxins into the body, even during prolonged use.
Massive Balls do NOT create vibration like Viball®; their effect is based on maximum weight with a comparatively small diameter.
To increase the effect, they can also be used in pairs or in combination with Viball®.

Pelvic floor workout: Massive Balls increase the effectiveness of our pelvic floor exercises in horizontal positions, as their high weight provides resistance to horizontally directed movements. This allows the muscles to be trained very effectively and in a sensually stimulating way from a different angle. 

Advanced users may also use smaller Massive Balls during pelvic floor exercises in an upright position, but only for short periods, as small, heavy balls need to be held much more firmly than larger ones. With well-trained pelvic floor muscles, gradual increases in weight can be used for vaginal strength training. 

Important: These heavy balls should only be used vaginally for short periods during pelvic floor exercises and should not be worn for extended periods in daily life.
For rectal use as anal balls, this limitation does not apply, as the rectal area is significantly more muscular than the vaginal area and can support considerably more weight.

Erotic effects:

 - Clearly perceptible presence of mass and weight in the genital area
 - Stimulating pressure in the anal region, on the G-spot or the prostate
 - Intensification of contact during intimate intercourse (“lost penis syndrome”)
 - Increased ability to reach orgasm and/or greater orgasm intensity.
