Arsenal Aluminum Tunnel Plug By Xr Brands

Anal training demands a toy that adapts to your progression—not a one-note plug that limits your exploration. The Arsenal Aluminum Tunnel Plug With Removable Core lets you customize depth, sensation, and intensity through its ingenious hollow design, so you control exactly how far you go.

What it is

The Arsenal Aluminum Tunnel Plug With Removable Core is a precision anal toy built around one innovative idea: a hollow tunnel that lets you remove the inner core and reconfigure your experience. Crafted from high-grade aluminum alloy, it combines a tapered insertion tip with a looped handle, making it equally comfortable for beginners exploring anal play and advanced users pushing their limits. The aluminum surface is smooth, non-porous, and responds to temperature, opening up sensory play techniques unavailable with standard silicone plugs.

What sets this plug apart is versatility through design. Remove the core to deepen penetration or insert secondary toys. Keep it in place for a more compact sensation. The removable mechanism transforms a single toy into multiple play configurations.

How to use a steel sex toy

Start by applying a generous amount of water-based lubricant to both the plug and your anal opening. Insert the tapered tip slowly, allowing your body time to relax and adjust. Use the looped handle to guide depth and control pace. Once fully inserted, you can experiment by removing the core, reinserting it, or leaving it out entirely to discover which configuration feels best for your body.

Advanced users can explore temperature play by warming or cooling the aluminum under running water before insertion. Extended wear sessions build tolerance and submission response; start with shorter periods and gradually increase duration as comfort grows. Combine this plug with Sex Chairs for hands-free wear during other activities, intensifying the sensory experience. Always prioritize your comfort and listen to your body's signals throughout play.

Care and storage

Disassemble the plug and removable core, then wash both components with mild soap and warm water immediately after use. Dry completely with a soft cloth before storage to prevent water spots on the aluminum surface. Store the plug in its provided bag in a cool, dry place away from direct sunlight. Keep the core separate if you prefer, or reassemble and store together—both methods preserve the toy's integrity and longevity.

Understanding anal training progression helps you get the most from any toy. Progression isn't about rushing deeper or larger—it's about building confidence, control, and sensation awareness over time.

Mistress Athena's training notes

This device has become central to my protocol for submissive progression. The removable core's psychological weight exceeds its physical presence—my submissives fixate on the possibility of depth change, creating anticipation that softens resistance before I ever deepen insertion. Watching them process the vulnerability of a hollow tunnel, knowing I can modify their sensation at will, reveals their surrender far more honestly than direct commands.

Aluminum's temperature conductivity gives me precise control over their nervous system response. A cool insertion shocks their awareness into sharp focus; warmth induces relaxation that breaks down psychological barriers. My submissives report that the smooth surface, combined with the psychological weight of the removable core, produces submission responses comparable to far more aggressive interventions. This teaches them that control operates through precision, not force.

Extended wear sessions using this plug demonstrate obedience and tolerance simultaneously. The looped handle allows me to adjust depth with minimal effort, keeping them uncertain whether I'll deepen their experience or maintain the current intensity. That uncertainty—that loss of predictability—accelerates their training more effectively than any fixed sensation. They learn to surrender not to pain or overwhelming stimulation, but to my will expressed through subtle, calculated adjustments.
