FlexiSpike Chastity Cage Size 0 CELLMATE

CELLMATE FlexiSpike Size 0 – A Compact Tool for Long-Term Male Chastity Control

The FlexiSpike Size 0 is the smallest chastity cage in CELLMATE's lineup, designed for users seeking not only effective restriction but also minimal visibility and a snug anatomical fit. Crafted from durable synthetic resin and hand-finished for precision, this cage is built for continuous wear – including in the shower or situations that demand absolute discretion.

The Tightest Model in the FlexiSpike Series

Size 0 offers an internal diameter of 34 mm and a length of 45 mm. It’s tailored for those with smaller flaccid penises or for users who prefer zero internal space. This size eliminates any possibility of erection and creates high discomfort in case of attempts, making it a powerful tool for sexual discipline and control.

High-Quality Resin – Durability, Stability, and Hygiene

The cage body is made from waterproof synthetic resin. The material is lightweight, free of sharp edges, and completely safe for skin. The hand-polished finish ensures a smooth surface and a perfect fit between the cage and rings. With no metal components, this device can be safely worn in the shower and in places with metal detection systems.

Engineered for Long-Term Wear

Thanks to its low weight and refined profile, the FlexiSpike Size 0 can be worn for hours – including during sleep. The material doesn’t react to sweat or body heat, and its structure prevents moisture accumulation. This is a product built for continuous use, not for trial sessions.

Adjustment System – Four Ring Sizes

The set includes four locking rings in 43 mm, 46 mm, 49 mm, and 55 mm sizes. This allows for precise compression at the base of the penis and scrotum, guaranteeing stability and preventing slippage. A properly chosen ring keeps the cage in place and prevents manipulation by the wearer.

The Key to Effective Lockdown

The rings are anatomically shaped and work seamlessly with the cage body, creating a fully enclosed system. The lack of rigid gaps eliminates the ability to slip fingers between the ring and the body – ensuring a secure lock with no escape possible unless the device is opened.

Silicone Spikes – Optional Pressure and Visual Signals

FlexiSpike Size 0 includes four sets of silicone spikes in black and pink. These can be mounted inside the cage using dedicated slots. Their presence increases pressure on the flaccid penis, reducing comfort and blocking arousal. The color of the spikes can also serve as a visual signal – e.g., the level of discipline or status in a D/s dynamic.

Configurable Pressure Tool

Spikes can be selectively used – in specific locations and quantities. No tools are needed for installation. This is a versatile feature that can serve as stimulation, restriction, or punishment, depending on how it’s applied.

Dual Locking System – Full Control, Two Modes

FlexiSpike offers two locking options. First, a traditional, secure brass padlock with two included keys. Second, an ABS Stealth adapter compatible with plastic single-use locks. Both systems are part of the kit and can be used interchangeably – for example, the brass lock at home, the Stealth Lock while traveling.

Single-Use Plastic Locks with Security Code

The Stealth Lock system uses five included plastic locks, each with a unique identification number. Once closed, the lock can only be removed by cutting it. This makes it ideal for remote keyholding scenarios – the number can easily be verified via video call or a photo. Additional 10-piece sets are available separately.

Daily-Wear Friendly Design

FlexiSpike Size 0 is built for comfortable, extended wear. The cage won’t cause pain, chafing, or mechanical issues. Its discreet profile doesn’t push against clothing, and the lightweight build makes it nearly unnoticeable during daily activity. With no metal, it’s airport and scanner-friendly.

Effective in Both Local and Remote Dynamics

Whether control is exercised locally or remotely, the FlexiSpike Size 0 supports full discipline. Since the cage cannot be removed without damaging the lock, cheating is impossible. The Stealth mode allows for unnoticeable use at work, school, or on business trips – always carrying the mental weight of surrendered access.
