1.Anesidoora Hollow Anal Plug 3 Sizes
This Hollow Anal Plug keeps things simple: polished stainless steel, a rounded tip, a fuller middle section, and a hollow opening running through the center. There’s no unusual texture or decorative detail. It’s a straightforward metal tunnel plug with three sizes to choose from.
The biggest reason to choose this Anesidora Hollow Anal Plug over a silicone model is temperature play. Stainless steel holds its temperature noticeably differently from silicone, making it a more interesting option for anyone who enjoys experimenting with cool or gently warmed sensations.
You can cool the plug in clean, cool water or gently warm it in comfortably warm water before use. The metal transfers temperature efficiently, so even a small change can be noticeable against the skin. I’d avoid extreme temperatures, though. Always check the surface against your inner forearm first, especially since metal can feel colder or hotter than expected.
Size Comparison
| Size | Total Height | Head Diameter | Maximum Body Diameter |
|---|---|---|---|
| Small | 72 mm | 25 mm | 30 mm |
| Medium | 90 mm | 30 mm | 40 mm |
| Large | 110 mm | 35 mm | 45 mm |
Price ：$19.54 – $22.94
Pros
- Excellent material choice for gentle warm and cool temperature play
- Three sizes with clearly specified dimensions
- Smooth, polished shape without extra ridges or textures
- Classic metal design with a hollow center
Cons
- Rigid metal can be uncomfortable if the fit is wrong
2.Clear Hollow Butt Plug Medical Grade Silicone
If the stainless steel plug above appeals to temperature play enthusiasts, this clear silicone model takes a different approach. Its biggest advantage is the choice of five sizes, ranging from a relatively compact 45 mm plug to a much larger 104 mm version.
What caught my attention is the removable cap, Rather than having a permanently open tunnel, this design allows the opening to be covered or left exposed. That’s a useful distinction from simpler hollow plugs, especially for buyers who want more flexibility in how the product is configured. The transparent material also makes the channel easier to inspect visually, although it doesn’t eliminate the need for thorough cleaning.
Compared with the rigid stainless steel model, this plug’s flexible silicone construction offers some give, but the larger sizes are still substantial. I also like the wide, flared base and relatively short neck on the smaller versions. The main trade-off is that the chunky head and removable cap design may not appeal to anyone looking for a slim, low-profile tunnel plug.
This would be my pick for someone who specifically wants a clear silicone tunnel plug with multiple sizing options and a removable cap. Just pay close attention to the head width rather than choosing by the S, M, or L label alone.
Price : $26.99
Pros
- Five size options covering a wide range of dimensions
- Removable cap offers an open or covered tunnel configuration
- Transparent body makes the internal channel visible
- Flexible silicone rather than rigid metal
- Wide flared bases across all five sizes
Cons
- Even the smallest size has a relatively wide 36 mm head

3.Dragon Fantasy Hollow Butt Plug
Most hollow butt plugs have a fairly predictable shape, but this Dragon Fantasy model takes a completely different direction. Instead of a smooth, rounded body, you get a collection of fantasy-inspired designs with sculpted scales, horns, ridges, and colorful orange-and-black patterns. Each variation has its own silhouette, so choosing between them is about more than just size.
The most unusual detail is the included flashlight. The hollow opening allows you to shine light through the toy for a closer look inside the channel. It’s an interesting extra that you don’t normally get with a basic tunnel plug. However, the flashlight provides illumination rather than actual camera-based viewing, so don’t expect it to function like a medical endoscope.
Personally, I think the fantasy styling is the main reason to consider this model. The marbled colors and detailed sculpting make it much more distinctive than the plain steel or transparent silicone options. There is a trade-off, though: pronounced ridges and protruding details aren’t ideal for someone who prefers a smooth, gradual shape. I’d also pay close attention to the base and neck design of the specific variation before choosing one for insertion.
Price：$39.59
Pros
- Multiple dragon-inspired shapes rather than one repeated design
- Distinctive orange-and-black marbled appearance
- Included flashlight for illuminating the hollow channel
- Detailed sculpting makes each variation visually different
Cons
- Raised horns and irregular textures may be uncomfortable for sensitive users
- Different shapes make sizing comparisons less straightforward
4.Jeweled Hollow Butt Plugs 3PCS
Instead of a thick, solid body, it uses a cage-like structure made from curved stainless steel wires. The open spaces give it a lighter, more delicate appearance, while the pink jewel set into the base adds a nice decorative touch.
What makes this design particularly appealing to beginners is its relatively narrow profile. The smallest version measures 105 mm long with a maximum width of 30 mm, while the medium and large increase to 36 mm and 42 mm. The tapered tip and slender 13 mm neck create a more gradual shape than the bulbous metal plugs earlier in this list. However, the wire structure is still rigid, so choosing a comfortable diameter remains important.
There’s also an important difference between this model and a traditional tunnel plug. Although the body is hollow, it doesn’t have a continuous enclosed tunnel. Instead, the curved metal wires form an open cage with gaps between them. That means you’re getting a completely different structure rather than simply a metal version of the silicone tunnel plugs.
That said, the narrow tip alone doesn’t make a product beginner-safe. The wire joints and spaces need to be completely smooth, with no sharp edges or pinch points. If you prefer a conventional smooth surface, a solid plug may still be the more comfortable starting point.
Price ：$17.99 – $22.49
Pros
- Open wire-frame design instead of a bulky solid metal body
- Smallest version has a relatively narrow 30 mm maximum width
- Gradually tapered shape with a slim 13 mm neck
- Pink jewel adds a decorative finish
Cons
- Open cage design doesn’t provide a true tunnel channel
5.Hollow Tunnel Butt Plug 4 Sizes
Some tunnel butt plugs look quite different from regular anal toys, but this stainless steel model keeps the familiar butt plug shape almost entirely intact. The main difference is the open tunnel running straight through the center, giving it a hollow structure without changing the traditional silhouette too much.
Unlike the longer, tapered Anesidora metal plug earlier in this list, this one has a shorter, rounder body. The four available versions range from 39 mm to 49 mm in head width and 60 mm to 75 mm in total height. That’s a relatively compact range, making the differences between most options less dramatic than those of some larger tunnel plugs.
One detail I find interesting is that the 40 mm version has a ribbed neck, while the other three have smoother necks. That gives buyers a slightly different design option without moving away from the classic rounded head. The ribbing may affect how the neck feels, although the product information doesn’t provide enough detail to judge that difference in actual use.
For me, the appeal here is familiarity. You get the weight and firmness of stainless steel, a recognizable butt plug shape, and an open center without fantasy textures or elaborate styling. If the first Anesidora metal plug feels too elongated for your taste, this rounder alternative is worth comparing.
Price ： $17.99 – $24.29
Pros
- Familiar rounded shape similar to a traditional butt plug
- Four options with relatively compact overall lengths
- True open tunnel running through the metal body
- Choice of smooth or ribbed neck designs
Cons
- Rounded heads are relatively wide, even on the smallest version
- Size progression isn’t consistent, with the ribbed version narrower than the 44.6 mm model

6.Ocean Goddess – Fantasy Butt Plug and Male Stroker 2 in 1
While the other hollow plugs focus on an open tunnel or traditional anal plug shape, this one combines a fantasy butt plug with a male stroker in a single silicone body. Its pink-and-green coloring, sculpted sea-creature details, and unusual dual-purpose construction make it look almost like a collectible fantasy figure.
Instead of a simple, smooth opening, Ocean Goddess uses a textured passage lined with raised rings and bead-like patterns. This gives the stroker side its own purpose, rather than treating the hollow center as an empty space. The product photos also show openings at both ends, making the dual-function concept easier to understand.
The integrated harness slots are another detail worth mentioning. They allow the toy to be attached to a compatible harness, opening up more positioning options than a typical standalone stroker. Still, I’d check harness compatibility carefully before buying. The slots are visible in the photos, but that doesn’t mean they’ll fit every strap system without adjustment.
There are three versions to choose from, and the differences go well beyond a few millimeters. The compact model measures 16 cm tall and weighs 442 g, while the largest reaches 18.9 cm and 721 g. That’s a fairly substantial piece of silicone, particularly if you’re considering the wearable plug function. The highly sculpted exterior also makes fit more complicated than with a smooth, tapered plug. Some raised details and wider sections could be demanding, regardless of the material’s flexibility.
I wouldn’t recommend Ocean Goddess as someone’s first butt plug. It’s better suited to buyers who already know what shapes and sizes they’re comfortable with and specifically want the extra stroker functionality. Compared with the other five products, its real advantage isn’t the tunnel itself but how many different design elements have been combined into one toy.
Price ： $67.49 – $80.99
Pros
- Combines a fantasy butt plug and male stroker in one design
- Internal rings and bead textures distinguish it from smooth tunnel plugs
- Integrated harness slots add wearable positioning options
- Three versions with different channel depths
Cons
- Bulky, sculpted exterior makes it less approachable for beginners
- Even the compact version weighs 442 g
- Textured internal channel is more involved to clean than a smooth tunnel
