Description
The Upgraded Resin Chastity Device with Metal Base Ring is one of our proudest 2025 innovations, carefully refined to address the common drawbacks of traditional resin cages.
Material & Weight Innovation
Weight is always a major concern for wearers. We wanted to keep the device lightweight while also ensuring improved hygiene and durability. That’s why we introduced a breakthrough aluminum alloy base ring—rustproof, antibacterial, sturdy, and lighter than steel.
The base ring adopts the same ergonomic curved structure used in our metal cage collection, with a reverse arch at the bottom for a secure fit around the testicles. Each set comes with four ring sizes, making it easy to find your best fit—or to transition later from resin to metal with confidence.
Improved Front & Cage Structure
At the front, the urethral opening has been upgraded to a wider oval design, offering more comfort and better compatibility with CBR jewelry. Larger ventilation openings on both sides improve breathability and allow you to adjust positioning with your fingers—especially useful for daily wear and convenient urination.
With a little practice, you can easily position yourself for clean use at standard urinals, not just toilets.
Comfort & Durability Upgrades
The inner diameter has been widened from 1.26 inches (32 mm) to 1.34 inches (34 mm), providing a noticeable increase in comfort. The locking system has also been reinforced with a through-locking mechanism, reducing wear and improving durability.
Additionally, we’ve shifted the lock core to a vertical top placement, making it easier to install and remove. This adjustment also positions the cage slightly lower, ensuring a tighter, more compact fit against the body—enhancing both comfort and restriction.
If you’re looking for a natural-shaped, lightweight device for daily wear—or simply want a thoughtfully upgraded alternative to traditional resin cages—the Upgraded Resin Chastity Device with Metal Base Ring is built to impress.
