The name “Styxx” might sound harmless at first. But one glance inside makes it clear that Cellmate has other ideas. The
Cellmate Styxx CBT Penis Cage combines chastity with an extreme form of cock and ball torture: the interior features small, sharp plastic pins that make their presence felt the moment the penis tries to swell. Staying still is rewarded. Arousal triggers an immediate reaction. This is anything but subtle—and that’s precisely what makes this black chastity cage so appealing.
Moreover, Styxx is more than just a provocative design. The open construction, various sizes, interchangeable cock rings, and two ways to lock the cage make this a particularly well-thought-out chastity system for enthusiasts of
male chastity, chastity, and CBT. The keyholder takes control; the wearer, above all, has very good reasons to remain acutely aware of it.
Chastity with a Vicious Edge
A standard penis cage prevents an erection. Styxx takes it a step further. The inside of the cage features multiple small plastic prongs. As long as the penis remains relaxed, there’s relatively little to worry about. If it tries to expand, the prongs make more pronounced contact with the skin. Arousal thus shifts from a reward to a sharp reminder of the agreement made.
According to the manufacturer, the pins are designed to
feel painful without piercing the skin. This places Styxx squarely in the realm of CBT—cock and ball torture—and makes it unsuitable as a chastity cage for anyone who simply wants to be locked up comfortably and discreetly. For a consensual D/s dynamic, that very constant threat can be an important part of the play. Styxx doesn’t need to say a word; the cage speaks for itself.
Open-work cage design for practical everyday use
The black cage features a striking open-work design with numerous cutouts. This not only gives Styxx its technical, almost futuristic look but also allows access to the skin while wearing it and showering. The penis remains confined while water can flow more easily through the cage.
Cellmate manufactures Styxx from high-quality resin and carefully finishes the cage. The rounded outer shape contrasts beautifully with what happens inside: on the outside, sleek, smooth, and understated black; on the inside, a small minefield for unwanted erections.
Different rings for a better fit
A good fit is essential for a chastity cage. The product images show
five different ring diameters: 43, 46, 49, 51, and 55 mm. This allows the fit to be better tailored to the wearer’s body.
The ergonomically shaped rings connect to the cage and together form the chastity system. Choose a ring that’s secure enough to hold the cage in place, but not so tight that it restricts blood circulation. Especially during prolonged wear, the right size is more important than the notion that tighter is automatically safer or better.
Traditional Lock or Discreet Stealth Lock
Whoever has the key has control—and Cellmate takes that quite literally with Styxx. The cage comes with a
traditional brass lock with two keys. Additionally, there is a plastic adapter that allows Styxx to be locked with a numbered disposable lock.
This second option is useful for remote key holding. The disposable locks have a unique identification code. This makes it possible to verify whether the original seal is still intact. Opening the cage without authorization therefore not only means escaping but also leaving evidence behind. Refill packs containing ten disposable locks are available separately.
Furthermore, the plastic locking mechanism does not feature a traditional metal padlock on the outside. This makes the design more discreet when a metal lock is undesirable or impractical.
With a urethral plug for urination while wearing
Styxx also comes with a
black flexible urethral plug/catheter. This has an opening that allows for urination while the cage is being worn. However, using a urethral plug requires significantly more knowledge and hygiene than simply wearing a chastity cage.
Urethral play carries risks, including irritation, damage, and infections. Therefore, use the plug only if you have experience with safe urethral play, maintain strict hygiene, and never force it. It is not necessary to use the plug to wear Styxx as a chastity cage.
Five cage sizes
Styxx is available in various lengths, so not every penis has to be squeezed into the same straitjacket. The available sizes are: When choosing a chastity cage, do not automatically opt for extra length “just to be safe.” A properly fitting chastity cage is designed to keep the penis securely in place while it is flaccid. Therefore, measure carefully before selecting a size.
Size 0: cage diameter 34 mm – length 45 mm
Size 1: cage diameter 39 mm – length 65 mm
Size 2: cage diameter 39 mm – length 85 mm
Size 3: cage diameter 39 mm – length 95 mm
Size 4: cage diameter 39 mm – length 105 mm
CBT Requires Clear Boundaries
The Cellmate Styxx is expressly intended for experienced, consensual chastity and CBT play. Gradually increase wear time and check the skin and blood circulation regularly. Remove the cage immediately if you experience numbness, severe discoloration, swelling, cuts, or pain that feels different or more intense than the agreed-upon CBT stimulation.
The internal prongs make monitoring especially important. What feels stimulating or challenging during a short session can cause irritation with prolonged pressure. When using the device with a keyholder, always agree in advance on boundaries, check-in times, and an emergency release option. Keep a key within reach in case of an emergency.

For those for whom chastity isn’t strict enough
The
Cellmate Styxx turns chastity into a game with consequences. The black, openwork design looks sleek and almost clinical, but the tiny pins on the inside reveal its true nature. Add to that a choice of different sizes, multiple ring diameters, and the option for numbered tamper-evident locking, and you get a chastity cage that makes the power dynamic particularly tangible.
We package your order carefully and with complete discretion. So from the outside of the package, there’s no way to tell that inside, a small black cage with particularly sinister intentions is waiting for its new owner.
