The Holy Trainer V4 Nub in Clear is a micro chastity cage that leaves nothing to the imagination, just 45mm of visible submission. Designed for those serious about male chastity, this ultra-short device keeps you locked tight and fully on display.

Crafted from transparent medical-grade bio-resin, the V4 Nub is lightweight, breathable, and discreet under clothing—yet brutally revealing in private. Its ergonomic shape stops erections before they start, making it perfect for long-term chastity wear, cock control, and keyholder domination.

The built-in lock system and forward pee hole make everyday wear clean, simple, and escape-proof. Whether you're self-locking or under strict orders, this cage ensures you're seen, denied, and owned.

Crystal clear. Deeply humiliating. Totally in control.
