The hollow tunnel design creates a unique hollow channel through the center, transforming how arousal builds as you sink deeper. Unlike traditional plugs, this one lets you feel the rim of the opening while inside, amplifying awareness of every stretch and fullness.\u003c\/p\u003e\n\n\u003ch2\u003eWhat It Does\u003c\/h2\u003e\n\n\u003cp\u003eWhen inserted, the tapered tip glides past your sphincter without resistance, then the body widens progressively to fill you completely. The tunnel structure means your inner walls press against the hollow channel rather than solid material, creating a sensation that's distinctly different from regular anal play. The metallic finish holds warmth beautifully, which intensifies contact with sensitive internal tissue. TPE material flexes slightly as your body relaxes around it, providing accommodation without losing structural integrity. Most users find this creates sharper awareness of their own muscle control compared to solid plugs.\u003c\/p\u003e\n\n\u003cp\u003eArousal builds differently with tunnel plugs because the hollow design amplifies every micro-movement you make. Clenching around the empty center generates heightened sensitivity that cascades upward toward your prostate or deeper pelvic structures. The wider body keeps pressure constant against your walls while the tunnel opening creates a focus point where all sensation concentrates. Many report orgasms arrive suddenly and fiercely because this configuration builds tension in patterns your body isn't accustomed to processing.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInsertable length: 4.5 inches (11.4 cm) with tapered tip\u003c\/li\u003e\n\u003cli\u003eMaterial: Medical-grade TPE with flexible yet supportive core\u003c\/li\u003e\n\u003cli\u003eBase diameter: Wide flared design for security and hands-free wear\u003c\/li\u003e\n\u003cli\u003eFinish: Metallic sheen with smooth polished surface\u003c\/li\u003e\n\u003cli\u003eDetachable base section for simplified cleaning and maintenance\u003c\/li\u003e\n\u003cli\u003eNon-porous construction suitable for all water-based lubricants\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow To Use It\u003c\/h2\u003e\n\n\u003cp\u003eBegin by relaxing completely—this plug's width demands you're genuinely ready for penetration rather than rushing the process. Apply generous water-based lubricant to both the tapered tip and your ass opening, then position yourself on hands and knees or leaning forward at the waist. Guide the narrow tip inside first, letting your sphincter adjust around the taper before pressing deeper. Once the widest part passes through, the flared base seats against your cheeks and locks everything in place securely.\u003c\/p\u003e\n\n\u003cp\u003eOnce seated, experiment with slow clenching cycles to awaken nerve endings around the tunnel opening. Rock your hips gently forward and back to shift pressure zones, then hold still to let sensation pool and deepen. After several minutes of this building contact, increase your movement intensity as arousal peaks. Many users find grinding against the base while squeezing rhythmically creates the mounting tension needed for serious climax—the combination of fullness and the hollow channel structure working together to overwhelm your senses.\u003c\/p\u003e\n\n\u003ch2\u003eWho It Suits\u003c\/h2\u003e\n\n\u003cp\u003eThis plug works best for people with prior anal experience who've trained their bodies past basic insertion and want progression toward extended wear or more challenging play. The 4.5-inch insertable length suits most body frames, though the width demands genuine readiness rather than casual experimentation. Solo users benefit from hands-free security during sessions, while partnered play opens possibilities for wearing it during other activities or having a partner control your positioning. Men interested in prostate stimulation find the deep positioning reaches that gland effectively. Skip this if you prefer compact toys, shallow penetration, or rigid plugs without flex.\u003c\/p\u003e\n\n\u003ch3\u003eWho Makes It?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNANMA Corporation manufactures anal toys with emphasis on TPE construction and user safety\u003c\/li\u003e\n\u003cli\u003eVisit the \u003ca href=\"https:\/\/cockringshop.com.au\/collections\/nanma-corporation\"\u003eNANMA Corporation brand page\u003c\/a\u003e →\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFeature Breakdown\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eSexual Benefit\u003c\/th\u003e\n\u003cth\u003eUser Experience\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTunnel Opening\u003c\/td\u003e\n\u003ctd\u003eHollow channel running through entire 4.5 inch length\u003c\/td\u003e\n\u003ctd\u003eAmplifies clenching sensations and focuses arousal onto a concentrated rim point\u003c\/td\u003e\n\u003ctd\u003eHeightened awareness of muscle engagement with sharper climactic response\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTapered Tip\u003c\/td\u003e\n\u003ctd\u003eNarrow 0.75 inch entry tapering to 1.6 inch body width\u003c\/td\u003e\n\u003ctd\u003eGuides insertion smoothly without forcing or requiring excessive preparation\u003c\/td\u003e\n\u003ctd\u003eRelaxed entry followed by satisfying fullness as the body widens inside you\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWide Flared Base\u003c\/td\u003e\n\u003ctd\u003eExpanded 2.2 inch diameter seat\u003c\/td\u003e\n\u003ctd\u003eAnchors securely during extended wear or vigorous solo sessions\u003c\/td\u003e\n\u003ctd\u003eComplete freedom to move and thrust without shifting or discomfort\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMetallic Finish TPE\u003c\/td\u003e\n\u003ctd\u003eNon-porous material with heat-conductive surface coating\u003c\/td\u003e\n\u003ctd\u003eRetains warmth to intensify sensation against internal walls\u003c\/td\u003e\n\u003ctd\u003eResponsive to body temperature with smooth glide and comfortable contact\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhere It Fits in Our Range\u003c\/h2\u003e\n\n\u003ch3\u003eAnal Sex Toys\u003c\/h3\u003e\n\u003cp\u003eThe Nanma tunnel plug sits in the intermediate-to-advanced category of anal toys, positioned between basic plugs and extreme play equipment. Choose this when basic insertable toys feel too modest but you want something wearable for extended sessions rather than hardcore penetration. The tunnel design offers the unique hollow sensation that standard anal toys can't match, making it a step sideways as much as forward for experienced users seeking novelty.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cockringshop.com.au\/collections\/anal-sex-toys\"\u003eBrowse all Anal Sex Toys →\u003c\/a\u003e\u003c\/p\u003e\n\n\u003ch3\u003eProstate Play Toys\u003c\/h3\u003e\n\u003cp\u003eFor cock owners targeting their prostate specifically, this plug's deep positioning and fullness create excellent contact with that gland during extended wear sessions. The hollow tunnel structure gives a different sensation profile than solid prostate massagers, generating arousal through pressure and muscular engagement rather than targeted vibration.

The metallic finish looked intimidating, but insertion proved easier than expected thanks to the genuine taper. Once the widest section cleared my sphincter, the sensation shifted completely—I suddenly felt the rim of that hollow channel in ways solid plugs never created. I wore it for thirty minutes during solo play, and the clenching-around-emptiness sensation built arousal exponentially faster than my usual plug. When I finally moved toward climax, the orgasm arrived with unexpected force and intensity. The detachable base made cleanup straightforward afterward. This earned permanent rotation status in my collection because no other toy creates that specific sensation profile.
