Small. Tight. Merciless.

The Holy Trainer V4 Nub Pink from Chastity Cages Co Holy Trainer Collection is chastity denial at its cutest and cruelest. At just 45mm in internal length, this ultra-short chastity cage offers zero room for erections and zero chance of escape. It’s one of the smallest devices available—built for serious submissives who crave long-term cock control.

Crafted from medical-grade bio-resin, the V4 Nub is lightweight, breathable, and discreet enough for 24/7 chastity wear. The front pee hole ensures easy hygiene, while the snug design keeps everything securely locked—no slipping, no stimulation, no mercy.

And that soft pink color? It’s more than just pretty. It’s a humiliating, visual reminder of who owns your cock now.

Slip in. Lock up. Stay owned.
