Description
The Leak-Proof Depth Funnel Cage is a uniquely engineered chastity design that achieves full inversion without heavy enclosure. Instead of surrounding the shaft, it uses a funnel-shaped structure that gently seals against the glans, guiding it inward and creating a deep, contained fit.
Externally, the cage integrates a support ring inspired by the ball-support concept — lifting and balancing the weight to keep the structure aligned and comfortable. The funnel’s opening allows for clean urination, and an intentional gap between the ring and the funnel ensures that the scrotum remains free from pressure.
Compared to traditional metal inverted cages, the reduced contact surface provides superior breathability and lightness, while maintaining full restraint. For improved stability during movement or long-term wear, pairing it with a chastity strap is highly recommended.
This model combines minimal coverage with complete control — a hollow yet sealed form that holds without force. Available in three sizes for a precise and comfortable fit.
