🕳️ Tunnel Plugs - Medium

Tunnel Plugs - Medium: an open design with a firm structure

We make Tunnel Plugs - Medium for experienced users who want a hollow plug with a defined shape. The central passage runs through the toy, while the Firm A-30 silicone supports the tunnel walls. Medium offers 10 cm of usable length in a shorter format than Long.

This design is not intended to collapse or fold for insertion. Choose a size you can already accommodate comfortably in a firm toy. A softer plug of the same nominal diameter is not a direct comparison.

Outer diameter and inner opening: two different measurements

Maximum usable diameter describes the widest part you insert. Neck diameter describes the narrower section behind it. Inner opening diameter describes the passage through the centre; it is smaller than either outer measurement.

Use Measure Your Pleasure above to check all three dimensions, along with usable length, total length and toy weight. The controls cover 21 sizes, from 5 to 15 cm in half-centimetre steps. Switching between cm and inches changes the display, not the selected size.

For example, the 10 cm model has an 8 cm neck and a 5.6 cm inner opening. The size in the selector is the outer diameter, not the opening size. Measurements describe the unloaded toy; pressure and fit can affect the opening during use.

Medium or Long?

Both models offer the same outer diameter, neck diameter and inner opening at each listed size. The difference is their length and weight.

• Tunnel Plugs - Medium: 10 cm (3.94 in) usable length, 14 cm (5.51 in) total length.
• Tunnel Plugs - Long: 15 cm (5.91 in) usable length, 19 cm (7.48 in) total length.

Choose by the dimensions you know are comfortable for you. Long is a different length option, not an automatic next step. If you are unsure, send us the measurements of a toy you already use and tell us what you would like to change.

Firm silicone and your choice of colours

These tunnels are made in Firm Shore A-30. This firmness is part of their shape-retaining construction. We offer Single for one colour throughout, or Transition for a blend between two colours.

With Single, your tip colour is used for the whole toy. With Transition, choose tip and bottom colours separately. See the Firmness, Color & Pattern Guide for the colour range.

Questions about the design

Can I fold it to insert a larger size?
No. These tunnels are not designed for folded insertion. Select the size by its full outer dimensions.

Is the opening the same size as the selected diameter?
No. The selector shows the maximum outer diameter. The inner opening is shown separately and changes with the chosen size.

Can another toy fit through the opening?
Compare its widest section with the listed inner opening and allow clearance. Do not force a tight fit; the fit can change when the tunnel is under pressure.

Can you make a custom size?
Contact us before ordering so we can check the dimensions and agree on the price and production time.

Care and use

Wash before and after use with warm water and mild soap. Clean the inner passage as well as the outer surface, rinse thoroughly and allow it to dry. Check the surface before use and follow our Safety, Hygiene and Lubrication guide for further care and lubricant guidance.

Use suitable lubricant and do not force insertion or continue through pain, numbness or bleeding. Diameter, usable length, firmness and your anatomy all affect the fit.
