The Holy Trainer V4 Nub in Black is strict, silent male chastity in its most compact form. At just 45mm in length, this micro chastity cage for men offers zero space for arousal - only pure, locked-down submission.

Crafted from medical-grade bio-resin, the Nub’s low-profile, ergonomic shape hugs close to the body, making it perfect for long-term chastity wear. No rubbing, no shifting. Just smooth, secure cock control that prevents erections before they even begin.

The forward-facing pee hole allows for discreet hygiene, while the matte black finish adds a bold, no-nonsense aesthetic to your full-time submission. Whether you're locked by a keyholder or practicing self-discipline, this cage delivers silent, total control.

Invisible in public. Inescapable in private.
Lock in. Stay down. Serve well.
