Cone Plugs – Gradual Diameter & Depth Training
Smooth tapered cones for progressive diameter and depth training. Insert as far as comfortable – the deeper you go, the wider it gets. Available in three lengths: Short (19 cm) for most users, Medium (37 cm) for intermediate depth, and Long (73 cm) for advanced depth training.

Cone plugs – the most precise tool for diameter and depth training
A cone plug is the simplest and most controlled stretching tool available. The tip starts narrow – just 1 cm at the smallest – and the body widens gradually and continuously to the maximum diameter at the base. There are no steps, no bulges, no sudden changes in resistance. You insert it as far as comfortable, hold the position, and the smooth taper applies steady outward pressure exactly where you are.
Because the gradient is perfectly continuous, you can feel your current limit with precision and push it forward in tiny increments – far smaller than any bulge toy allows. This makes cone training the most effective method for both diameter and depth progression, and the approach of choice for users working at advanced levels.
Choosing the right length
All three cone plugs share the same principle but differ in usable length – 19 cm, 37 cm and 73 cm. The length you need depends on your depth training goals.
The Cone Plug Short (19 cm) is the right starting point for most users. It covers a wide diameter range in a manageable length and is effective for both diameter and depth training. The Cone Plug Medium (37 cm) is the next step for users who have become comfortable with the Short and want to work toward greater depth. The Cone Plug Long (73 cm) is a specialist tool for advanced users pursuing extreme depth training – not suitable for beginners.
Diameter training with a cone plug
Insert to a comfortable depth, then apply gentle outward pressure by pushing slightly further. Hold the position and breathe. The steady pressure gradually allows you to go deeper – and because going deeper means going wider, diameter and depth training happen simultaneously. You can also focus on one dimension: stop at a fixed depth and hold for diameter training, or push for depth while staying within a comfortable diameter range.
How cone training fits into a broader routine
Cone plugs work best as part of a complete training routine. Many users combine cone sessions for active diameter and depth work with T-Plug daily wear for passive diameter training. The cone pushes your limit in focused sessions; the T-Plug consolidates progress over time. For an overview of how different training methods work together, read our Stretching Styles and Techniques guide. For depth training at advanced levels, see our Advanced Practices guide.

Frequently asked questions
What is a cone plug used for?
A cone plug is used for progressive diameter and depth stretching training. The smooth, continuous taper allows precise control over the depth and pressure of stretch. Insert as far as comfortable and let the taper apply steady outward pressure at exactly that point. Going deeper automatically means going wider, so cone training progresses both dimensions simultaneously.
How do I choose between Short, Medium and Long?
Start with the Short (19 cm) unless you already know you want to train beyond 19 cm depth. Progress to the Medium (37 cm) when the Short feels fully comfortable at your target diameter. The Long (73 cm) is for advanced users working at depths that exceed what the Medium can offer – it is not a beginner tool.
How do I choose the maximum diameter?
Choose a maximum diameter 2–3 cm above your current comfortable limit. You don't need to reach the maximum immediately – the cone lets you train up to it gradually. Starting with more range gives you room to grow without needing to order a larger cone soon. If you're unsure, contact us and we'll help you choose.
Is a cone plug the same as an anal trainer?
A cone plug is a type of anal trainer, yes – but more specifically designed for progressive stretching than most products marketed under that name. The key feature is the continuous smooth taper from a very narrow tip to a large maximum diameter, which allows extremely precise and gradual progression. Our cone plugs are also suitable for vaginal stretching training.
