Made from high-quality TPE material, it balances flexibility with structural support. See the full range in our tunnel plugs collection to compare similar styles and find what suits your preferences best.
The tunnel design sets this apart from solid plugs. You can also view our steel butt plugs selection if you prefer firmer, heavier alternatives with different sensations and heat retention properties.
Constructed from medical-grade TPE, this plug is body-safe and non-porous. TPE material is hypoallergenic and free from harmful chemicals. Clean with warm water and toy cleaner before and after use. The smooth surface minimises friction when properly lubricated.
Pair this plug with compatible vibrators for added stimulation. Many users enjoy wearing it during partnered activities for heightened sensation. Experiment with different positions to discover what feels most comfortable and intense.
Wash thoroughly with warm water and mild soap after each use. Dry completely before storage. Store in a cool, dry place away from direct sunlight and extreme temperatures. Keep away from sharp objects that could puncture the material.
The tunnel design creates a distinctive sensation that differs significantly from solid plugs. The open centre allows internal pressure and stimulation while the wide body delivers fullness. Many users report a unique blend of firmness and flexibility that feels satisfying rather than overwhelming.
Insertion feels gradual thanks to the tapered tip. Once fully inserted, the wide base provides reassuring contact and stability. The tunnel opening creates subtle sensations as muscles contract and relax around it. Results depend on individual anatomy, sensitivity levels, and personal preference for fullness and pressure.
Anal exploration requires products designed specifically for comfort and safety. This plug prioritises both through its tapered entry and supportive structure. The tunnel design offers something genuinely different from standard anal toys, giving you access to sensations you cannot experience elsewhere. For people seeking confident, pleasurable exploration, having the right tool makes all the difference. The detachable base removes common frustrations around cleaning and maintenance, so you spend less time on upkeep and more time enjoying yourself. Quality construction means this becomes a reliable part of your collection that you'll actually reach for repeatedly.
I approached this plug expecting standard performance, but the tunnel design genuinely changes the experience. The tapered tip made insertion straightforward even without excessive lubrication, though I still used plenty for comfort. Once fully inside, I felt the tunnel structure create interesting sensations as my muscles moved—it's different from solid plugs in a way I actually preferred. The wide base stayed secure throughout movement without feeling uncomfortable. Cleanup was genuinely easy with the detachable section; no struggling to get into tight spaces. The metallic finish looks appealing even during storage. My only observation is that the 4-inch insertable length suits experienced users; newcomers to anal play might prefer starting with something shorter. For regular use, this has become my go-to option. Individual results may vary based on anatomy, sensitivity, and usage.

Medical-grade TPE construction creates a body-safe anal plug featuring an open tunnel centre rather than solid construction. The tapered tip guides insertion smoothly while the wide flared base prevents slipping during use. The detachable base section simplifies cleaning and maintenance, making the Nanma Power Sealed Open Wide 4 Inch Tunnel Plug practical for regular use. The metallic finish provides visual appeal alongside functional design suited to experienced explorers.
The hollow tunnel design creates sensations that solid plugs cannot replicate, allowing internal pressure and subtle movement around the opening. Muscle contractions produce interesting feedback as your body adjusts to the structure. Once fully inserted, the wide base provides reassuring contact and stability throughout use. The tapered entry feels gradual and manageable with proper lubrication. Individual results may vary based on anatomy, sensitivity, and usage.
Flexible TPE material adapts to individual anatomy rather than forcing a rigid shape, reducing pressure points common with inflexible alternatives. The tapered tip minimises insertion resistance while the wide base distributes pressure evenly across your body. Smooth surface texture minimises friction when properly lubricated. The 4-inch insertable length suits experienced users who've prepared adequately. Proper lubrication and relaxation before use ensure comfort throughout your session.
Experienced explorers seeking sensations beyond standard plugs, couples incorporating anal play into partnered activities, and solo users desiring the unique tunnel design benefit significantly. Those comfortable with 4-inch depth and seeking distinctive firmness paired with flexibility find this plug delivers exactly what they want. People who value easy cleanup and detachable components appreciate the practical engineering alongside the sensation profile this plug offers.
The detachable base section removes common cleaning frustrations by providing access to all surfaces without struggling with tight spaces. Wash thoroughly with warm water and mild soap after each use, then dry completely before storage. Medical-grade TPE resists degradation when stored away from direct sunlight and extreme temperatures. Regular maintenance prevents material deterioration, ensuring the Nanma Power Sealed Open Wide 4 Inch Tunnel Plug remains reliable through repeated use and extended ownership.
