Theros® Massive Balls are the only vaginal or anal balls worldwide made of solid, hypoallergenic implant-grade steel AISI316L. Like Viball®, they do not release any toxins into the body even when used for a long time.

Pelvic floor training: Massive Balls increase the efficiency of our pelvic floor exercises in horizontal positions, because their high weight provides resistance to horizontal movements. This allows the muscles to be trained very effectively and erotically from a different angle.

Advanced users can also use smaller Massive Balls during pelvic floor exercises in an upright position. In addition, small and heavy balls are a greater challenge because they must be held even more firmly than large ones. With well-trained pelvic floor muscles, you can gradually increase the weight to perform vaginal strength training.

Important: These heavy balls should be used vaginally only as a weight during active pelvic floor exercises and not worn for long periods in daily life! They also do not produce vibrations during movement like Viball®.

When used rectally as anal balls, this problem does not exist, as the rectal area is significantly more muscular than the vaginal area and can bear considerably more weight.

Erotic effects:

- Intensely perceptible presence of mass and weight in the genital area
- Stimulating pressure in the anal region, on the G-spot or prostate
- Intensification of contact during intercourse ("lost penis syndrome")
- Increase in orgasm ability or orgasm intensity.
