Anal tunnel plugs

Anal tunnel plugs for a stable opening and a completely hollow passage through the anal canal

A plug designed to hold the entrance open and provide an accessible internal tunnel

Anal tunnel plugs are defined by their hollow structure that keeps the anus spread while leaving the inside accessible. Once inserted, the tunnel prevents the ring from closing and maintains a solid circular stretch. This open conduit allows adding a finger, lubricant or compatible accessory without removing the plug. The body stays open, stretched and available, creating a unique sensation of constant exposure.

A distinctive stretching effect created by a thick outer wall and a rigid internal cavity

Unlike solid plugs, tunnels create circular pressure while leaving the center empty. The user feels a firm ring around the entrance rather than a filled space. Larger outer diameters increase the stretch; wider internal tunnels increase access. Advanced users enjoy this contrast: external tension with internal openness.

Stability supported by a wide base, flared silhouette and crush-resistant structure

A tunnel plug must remain firmly in place despite being hollow. The base prevents over-insertion, and the reinforced walls stop the tunnel from collapsing under muscle pressure. Silicone maintains shape, structured TPE adds slight flexibility, and rigid PVC delivers maximum stability.

Types of anal tunnel plugs by width, depth and intended use

Short tunnels for surface-level opening

They keep the entrance spread without penetrating deeply. Perfect for direct access at the anal ring.

Long tunnels for deeper access

These models open a larger portion of the canal and intensify the stretching effect.

Wide tunnels for maximum accessibility

They offer strong external stretch with a spacious internal cavity.

Materials: high-density silicone, structured TPE, rigid PVC

Each material changes stability, comfort and resistance to pressure.

Choosing a tunnel plug: outer diameter, inner diameter, length, rigidity and comfort

The outer diameter determines the stretch. The inner diameter controls access. Length determines how much of the canal stays open.

Safe use: controlled insertion, generous lubrication and gradual removal

Use plenty of water-based lubricant, insert slowly, ensure stable seating, and clean the internal tunnel carefully after use.

Frequently asked questions about anal tunnel plugs

What is an anal tunnel plug for?
To hold the entrance open while keeping the canal accessible.

Is it suitable for beginners?
Only in small sizes.

Can the tunnel collapse?
No, not with proper material thickness.

Can a finger or accessory pass through it?
Yes.

Can muscle contractions push the plug out?
Not if the base is wide enough.

What lubricant should be used?
Thick water-based lubricant.
