The Princes Wand with Glans Ring is a popular choice for fetish and SM enthusiasts.
You place the ring around the glans and insert the plug into the urethra.
The plug is open-ended, allowing fluids to pass while still inserted.
The ring is made of surgical stainless steel.
It comes in two different sizes, and the glans ring has a diameter of 28 mm and 30 mm, respectively.
The actual plug is 7.5 cm long and 0.6 cm in diameter.
