Hi dhernash3, I am not sure exactly what you mean but this was all I could find about it.
Anal plugs are foam, cup-shaped devices that sit inside the rectum in order to prevent bowel leakage.
They are made from medical grade foam that is slightly absorbent but can allow air to pass through.
Individual plugs are covered in a dissolvable film which keeps the plug in a size and shape similar to a suppository or small tampon for easy insertion.
Once in the rectum, moisture from the lining of the rectum dissolves the film and the anal plug expands to a cup or mushroom shape.
They can stay in place for a maximum of 12 hours but must be removed in order to pass stool.
They have a string attached for easy removal.
