Guardian Chastity Cage Black Size 0 CELLMATE

CELLMATE Guardian Size 0 – minimalist lock, maximal discipline

The Guardian Size 0 is the smallest model in CELLMATE’s prestigious line of male chastity cages — engineered for total anatomical precision, daily practicality, and unwavering control that makes no space for compromise. This ultra-compact design was created for those who understand that true submission begins where space ends. Made from premium-grade resin, 100% waterproof, and completely metal-free, the Guardian Size 0 fuses technical perfection with silent, lasting, inescapable denial.

Compact dimensions – close-fit control, resistant to any attempt

With a diameter of just 34 mm and a length of 45 mm, Size 0 is the most compact option in the Guardian series. Designed for men with very small flaccid sizes or those who intentionally seek extreme tightness as a form of everyday discipline. Its tiny volume renders any erection physically impossible — even the attempt is immediately halted. The cage hugs the body like second skin, leaving no room for illusion. This isn’t comfort. It’s control.

Durable technical resin – discreet, hygienic, resilient

Guardian Size 0 is entirely made from moisture- and temperature-resistant synthetic resin. It won’t deform under body heat, won’t irritate the skin, and won’t lose its shape even with continuous, long-term use. Its metal-free design ensures full compatibility with metal detectors — you can wear it while traveling, at airports, at work, or anywhere discretion is essential. Invisible to others, but constantly present to you.

Hand-polished finish – precision in every detail

Each Guardian cage undergoes hand-finishing to remove sharp edges and ensure comfort during extended wear. The components are fitted with millimeter-level accuracy, minimizing friction and preventing asymmetrical pressure points. Despite the extreme tightness, this device offers full safety for long-term use. It may be small, but it never compromises.

Four locking rings – anatomical control with zero wiggle room

Included are four ergonomically shaped base rings — 43 mm, 46 mm, 49 mm, and 55 mm. These rings are critical for keeping the cage in place, preventing shifting, and blocking internal manipulation. Each ring is engineered to wrap around the penis base and scrotum securely but without discomfort. Once locked, there’s no unintentional movement — only the key can end this closure.

Unyielding lock – no gaps, no excuses

When the Guardian Size 0 is secured with the proper ring, it becomes a compact, sealed structure. No room for fingers, no space for skin movement — just absolute confinement. This isn’t a novelty item. It’s a locking system engineered with surgical precision and zero leniency.

Dual locking options – physical and psychological control

Guardian Size 0 supports two locking systems. The first is a classic brass lock with two physical keys — solid, heavy, symbolic. The second is a lightweight ABS adapter for disposable plastic Stealth Locks. Both are fully compatible with the cage and rings. The choice depends on the type of control the dominant prefers.

Stealth mode – for remote authority

Included are five single-use plastic locks, each with a unique serial code. Once secured, they cannot be removed without cutting. The code allows remote verification — a photo or video is enough to prove the device remains sealed. Perfect for long-distance D/s relationships where trust is enhanced by unarguable control.

Discreet and wearable – technology locked in silence

Guardian Size 0 was designed to disappear under clothing. Its sleek, compact shape avoids bulging, remains invisible under trousers, and doesn’t interfere with daily movement. No metal means no alarms at security checkpoints, and water resistance allows use in the shower or during physical activity. It doesn’t get in the way — but it never lets you forget it’s there.

Irreversible closure – a decision that lasts

No matter which locking method is chosen, Guardian Size 0 only does one thing: lock. Only the person with the key or the cutter can break that seal. For the wearer, there’s no escape route — access to their own body has been revoked, and control reassigned. This device doesn’t ask. It doesn’t suggest. It commands.

Guardian Size 0 – a lock that speaks volumes without a word

CELLMATE Guardian Size 0 is a device that leaves no room for compromise. Its extremely compact, precision-engineered form serves a single purpose: to revoke access and hand over control.
