FlexiSpike Chastity Cage Size 0 CELLMATE

CELLMATE FlexiSpike Size 0 – A Discreet, Tight Chastity Device Built for Real-World Use

The FlexiSpike Size 0 is CELLMATE’s most compact male chastity cage, designed for users who value total control, precise fit, and the ability to wear the device daily without compromising hygiene or discretion. Its body is made of durable resin and entirely metal-free, making it safe for water contact and invisible to security systems. This is a tool that merges technical functionality with options for personalization, making it suitable for long-term wear and full integration into D/s relationships.

Size 0 – The Smallest Model in the Series

FlexiSpike Size 0 features an inner diameter of 34 mm and a length of 45 mm. This model is designed for users with a smaller flaccid size or those who prefer a tight, uncompromising fit. In this size, the absence of erection space is not a side effect – it’s a design principle. The cage clings tightly to the body and leaves no room for any muscular tension without immediate pressure feedback.

Durable Resin Body – Long-Lasting and Weather-Resistant

The cage is made from high-quality synthetic resin that offers rigidity, does not warp from body heat, and won’t degrade with prolonged moisture exposure. It can be worn in the shower, during sleep, or physical activity. With no metal components, it’s the ideal choice for users traveling by air or wearing the device in environments with metal detection.

Hand-Finished Craftsmanship – Precision and Safety

Each FlexiSpike cage is hand-finished to ensure smooth edges and perfect alignment. This process prevents chafing, asymmetrical pressure, or contact points that could lead to injury during extended wear.

Locking Ring System – Four Sizes for Ideal Fit

The kit includes four ergonomic locking rings in diameters of 43 mm, 46 mm, 49 mm, and 55 mm. This allows personalized adjustment to the user’s anatomy. The right ring prevents slippage, and its shape ensures comfort during long-term wear. Together with the cage, it forms a sealed system that cannot be removed without unlocking.

Stability Without Compromise

Ring selection is not just about comfort – it guarantees that the wearer cannot tamper with the device from within. The absence of internal space eliminates the ability to move skin or insert fingers between the ring and the body.

Silicone Spike Module – Physical and Psychological Pressure

CELLMATE FlexiSpike includes four sets of silicone spikes – two black and two pink. These can be inserted into the interior of the cage using dedicated mounting slots. The spikes increase pressure on the flaccid penis, limiting freedom and ensuring constant awareness of the device. The user has no say in their use – it’s the dominant partner who decides when and how they’re applied.

Soft Form, Firm Purpose

Though made from soft silicone, the spikes are firm enough to serve their intended function. They do not harm the skin, but provide a continuous sensory reminder – reinforcing the fact that access to pleasure has been physically denied. They can serve as an aesthetic or functional component, depending on context.

Locking System – Brass Padlock and Stealth Mode

Two locking systems are included: a traditional brass padlock with two keys, and a modern ABS adapter designed for single-use plastic locks. Both mechanisms are fully compatible with the cage and ring system. Whether the scenario calls for a visible or invisible lock is entirely up to the user or their keyholder.

Stealth Mode – For Discreet Wear and Remote Supervision

The FlexiSpike comes with five single-use plastic locks with unique serial numbers. Once applied, these locks can only be removed by physically cutting them. This system is ideal for remote supervision – codes can be verified via photo or video. Additional 10-pack lock sets are available separately.

Everyday-Ready Construction

Thanks to its compact size and neutral appearance, the FlexiSpike Size 0 can be worn throughout the day, in any situation. It doesn’t show under clothing, doesn’t cause unexpected movement, and its metal-free construction means it won’t trigger alarms at security checkpoints. It’s ideal for those who want their chastity enforced even in public spaces.

Direct Control Over Access

Regardless of the locking system used, the wearer cannot access their body without damaging the lock. In D/s relationships, this is non-negotiable – access is granted only by the person holding the key or code.
