Invasion Hollow Silicone Anal Plug by XR Brands is a semi-rigid anal plug featuring a hollow core design for versatile access. Available in small (3.75 inches total, 1.5 inches diameter) and large (5.25 inches total, 2.15 inches diameter) sizes, it combines premium silicone construction with a flared base for security. The tapered tip facilitates comfortable insertion, making it suitable for both beginners exploring anal play and experienced users seeking reliable performance.
The hollow core architecture creates unrestricted internal access while the tapered tip guides insertion smoothly. The semi-rigid silicone maintains structural integrity throughout use, adapting to natural movement without losing shape. This design enables exploration of sensations that solid plugs cannot replicate, particularly for those interested in cumulative or layered stimulation approaches.
Premium silicone construction delivers both flexibility and durability that inferior materials cannot match. The non-porous surface supports straightforward cleaning and permits thorough sterilization through boiling or bleaching methods. Those seeking additional options in anal exploration can discover our weighted butt plugs at Adultsmart, which provide different sensations through mass and pressure distribution.

Pairing this plug with medium butt plugs of different shapes creates varied sensations across multiple sessions. Many find that alternating between different plugs over several days allows the body to become progressively more receptive to deeper or larger insertions. Combining anal plug wear with other forms of stimulation can intensify overall sensation through layered focus.
After each use, rinse the plug with warm water and mild soap, ensuring all residue is removed from both external surfaces and the hollow interior. Allow it to air dry completely before storage. For maximum hygiene, boil the plug in water for five minutes monthly or soak it in a bleach solution according to sterilization guidelines. Store in a clean, dry location away from extreme heat or direct sunlight, which can degrade silicone over time.
Premium silicone construction ensures body-safe, non-porous material that resists bacterial colonization and supports thorough sterilization. The semi-rigid composition maintains structural integrity while allowing natural flexibility during wear. Silicone's durability means this plug withstands repeated use and cleaning cycles without degradation, making it a reliable long-term investment in anal exploration equipment.
Suits people transitioning from smaller plugs to larger dimensions, as well as those specifically interested in hollow-core designs for unique internal sensations. The tapered tip makes it accessible for beginners, while the two size options accommodate both newcomers and experienced practitioners. Those seeking reliable, sterilizable anal equipment with thoughtful engineering will appreciate the flared base security and premium material quality.
For people frustrated by solid plugs that provide only pressure sensation, the hollow core design creates access to sensations that closed-end plugs cannot deliver. The tapered tip removes the intimidation factor that many feel when first attempting anal insertion, transforming what feels like forcing entry into a gradual, manageable process. For those curious about whether anal play could work for their body, discovering that a well-designed plug with proper lubrication creates comfort rather than discomfort shifts assumptions about what this form of exploration actually feels like. The flared base provides security that allows focus to shift from worry about retention to actual sensation, letting pleasure develop rather than anxiety dominating the experience.
Our independent testers evaluated insertion ease, structural stability during active wear, and material durability across multiple sterilization cycles. The tapered design consistently facilitated smooth entry without requiring excessive force, while the flared base remained securely positioned throughout testing sessions.
Testers noted that the hollow core provided distinctly different sensations compared to solid plugs, with internal access creating possibilities for layered stimulation approaches. The premium silicone maintained its shape and integrity through repeated boiling and bleaching cycles without visible degradation. Individual results may vary based on anatomy, sensitivity, and usage patterns.
