# Expandable Inflatable Butt Plug – Manual Size Control

## Product Overview

The ST-AP-EXP47 is a non-powered inflatable butt plug with a three-lobe insertable body, flared base, flexible air hose and hand-squeeze bulb. The bulb provides manual size adjustment; the product has no vibration, battery, app or charging requirement.

This product is sometimes described as an anal trainer because its size can be adjusted gradually. That term describes the use format only: it is not a medical device and does not promise lasting physical changes or a performance outcome.

The maximum pictured inflated width is a product dimension, not a recommended target. Do not attempt the maximum size simply because the product can reach it.

## How to Use More Safely

1.  Inspect the plug, hose, bulb, valve and flared base before every use. Do not use if any part is split, loose or leaking.
2.  Confirm the plug is fully deflated. Apply plenty of water-based lubricant.
3.  Insert slowly without force. Keep the flared base outside the body and the bulb and valve within reach.
4.  If you choose to inflate, use only small increments and pause between squeezes. Stop at the first sign of pain, numbness, bleeding, marked pressure or discomfort.
5.  Release all air and confirm the insertable body is fully deflated before slow removal.

This adjustable product is not an automatic beginner recommendation. Experience, anatomy and comfort vary; choose a smaller fixed-size flared plug if you are uncertain about size control.

## Cleaning and Storage

Store fully deflated in a cool, dry place with the hose unkinked. Do not share without a new compatible barrier and full cleaning.

## Frequently Asked Questions

### Does it vibrate or require charging?

No. It uses a manual bulb and has no powered functions.

### What size is shown before inflation?

The media labels the three uninflated lobe widths as approximately 28, 32 and 36 mm and the insertable length as 130 mm.

### Is 120 mm a recommended inflation size?

No. It is the largest pictured product width, not a usage recommendation. Increase only in small increments within your comfort and never force expansion.

### How should it be removed?

Release all air, confirm the plug is fully deflated, add lubricant if needed and remove slowly without force.
