This is a penis plug to insert in the urethra.
First and foremost, this plug has a ring that is meant to sit around the glans.
What makes this plug special is that it is designed with a hole all the way through. This means that all liquids can pass through while you have this plug inserted.
For many this penis plug is both titillating and painful, and for some also a mortifying feeling to use a penis plug like this.
The plug is manufactured from steel. It is 5.3 cm long and has a diameter of 8mm, 9mm eller 10 mm. The ring has a diameter of approx. 3 cm.
