What's in the box, and what it does

The Power Sealed Open Wide Tunnel Plug by NANMA combines a hollow-channel design with solid engineering to deliver sensations that most standard butt plugs cannot offer. The tapered tip guides insertion smoothly, while the expanded body provides fullness without overwhelming the user. TPE construction allows the material to flex and adapt to your body while the tunnel remains reliably open during use.

What distinguishes this plug is its detachable base system. The wide flared safety base locks everything in place during play, then separates cleanly for proper washing. The metallic finish feels substantial and looks striking, while the flexible TPE keeps pressure comfortable even during extended sessions.

Key features

  • Open tunnel design: A hollow channel through the centre creates access and unique sensations that solid plugs simply cannot replicate.
  • TPE material: Flexible construction adapts to your body shape while staying firm enough to keep the tunnel patent and supportive.
  • Detachable base: The wide flared safety base removes easily, making cleaning and storage straightforward without compromising security during wear.
  • Tapered tip: A smooth, tapered insertion point guides entry without forcing, reducing discomfort and simplifying warm-up.
  • Metallic finish: A bold surface appearance combines durability with visual appeal.

  • Insertable length: 4.5 inches (11.4 centimetres).
  • Colour: Metallic finish.

How to use a butt plug step by step

Begin by applying generous amounts of quality water-based lubricant to both the plug and your opening. Relax for a few moments before insertion—tension makes entry uncomfortable. Position yourself comfortably, then gently guide the tapered tip inward using steady, even pressure. Let your body set the pace; pushing too hard defeats the purpose of the taper. Once fully inserted, the tunnel channel becomes part of your sensation, especially if you combine it with other forms of stimulation or partner activity.

Once in place, the wide flared base keeps everything secure, so you can focus on the experience. If you explore Flexible Silicone P-Spot Beads, you'll notice how tunnel designs pair well with internal stimulation. To remove, apply extra lubricant, relax fully, and gently ease it out using slow, controlled movements. Clean thoroughly with warm water and mild soap immediately after use.

Is it right for you?

This plug suits experienced players who want what Anal Cleansing products keep properly maintained during regular use.

Great if you…
  • Have tried standard plugs and want the access and unique sensations a hollow tunnel design delivers.
  • benefit easy cleaning and appreciate a detachable base that separates for thorough washing.
  • Prefer TPE flexibility over rigid materials, wanting something that adapts to your body shape.
  • Appreciate build quality and want a plug that holds its shape and keeps the tunnel reliably open.
Maybe not if you…
  • Are brand new to anal play and not yet comfortable with insertable sizes at 4.5 inches.
  • Prefer solid plugs for straightforward stretching without the complexity of tunnel sensations.
Always use generous water-based lubricant, relax fully before insertion, and never force the plug—gentle pressure and patience prevent discomfort and injury. Safety first. Use only toys with a flared base or retrieval cord — anything without one can be drawn inside and require medical removal. Go slowly, use plenty of lubricant, and seek medical advice for bleeding or lasting pain. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Stop use and seek medical advice if you experience pain, numbness, swelling, discolouration, bleeding or persistent irritation.

Care and storage

Wash the plug and its detachable base thoroughly with warm water and mild soap immediately after use. Dry both components completely before reassembling or storing. Keep it in a clean, cool, dry place away from direct sunlight and heat. TPE material can degrade if exposed to extreme temperatures or stored near other materials that might cause discolouration. Store separately from other silicone items to prevent material transfer.

Tunnel-style plugs open up possibilities that many players don't realise exist until they try one properly made. Understanding how hollow designs work, what sensations to expect, and how tunnel play fits into a broader practice helps you get the most from your experience. Our guide to Butt Plugs For Gays covers tunnel designs, sizing, and technique in depth.

What to expect

by Risetob

The 4.5-inch insertable length sits comfortably for most experienced players—long enough for real sensation, not so extreme that it feels intimidating. First-timers to tunnel play often expect the hollow channel to feel odd, but most find it adds a distinctive layer of sensation that solid plugs cannot replicate. The TPE material stays flexible enough to accommodate your body while maintaining enough firmness that the tunnel doesn't collapse under pressure.

Cleaning is genuinely straightforward because the base detaches. This matters more than it sounds—plugs where the base is fused are awkward to wash properly, and residue can build up inside a sealed tunnel. Separating the components here means you can access every internal surface with a cloth or soft brush.

The metallic finish is durable and does not degrade with normal care. Most users report that this plug holds up well to regular use over months, with no warping or loss of structural integrity. The tapered insertion tip remains smooth and does not develop rough spots, which is not true of all TPE plugs.

Sizing up from standard plugs to tunnel play sometimes surprises people—some find tunnel sensations more intense than they expected, while others find the hollow design actually feels less invasive than a solid plug of the same outer dimensions. Either response is normal. Warm-up matters more with this style because the body needs time to relax into the fuller shape.

How it compares

Style Design approach Best suited to Cleaning
Tunnel plug (this one) Hollow channel through centre with detachable base Experienced players wanting access and unique sensations Detachable base allows thorough internal cleaning
Standard solid plug Solid body with fixed base Players new to anal or seeking straightforward fullness Easier to wash externally; internal tunnel space absent
Vibrating plug Motorised vibrations in solid or hollow body Players prioritising motorised stimulation intensity Battery compartment requires careful drying; more complex care
Inflatable plug Pump-operated sizing via internal air chamber Players wanting adjustable fullness without buying multiple sizes Valve seal requires attention; prone to slow leaks over time
