This penis plug has a steel ring to prevent over insertion (as opposed to a widened "hilt" area on other models). It is great for a simulated pierced look. Made of aluminum alloy, with widest portion at 9.5mm diameter, and a little less than 2" insertable length.

The plug also has a thru-hole drilled through its length, allowing the wearer to urinate and ejaculate without removing the plug.

Diameter = 9.5mm (at it widest point)
Total length = 55mm, with 32mm insertable length. That's about two inches, with 1.25 inches of insertable length.

Recommended for use with sterile surgical lube.
