Wow! This is one highly stimulating device. A full cage that starts with a triple stainless steel cock ring and builds a full stainless steel cage around the shaft. Caged like the animal that it is! The rings on the cock sleeve portion are lightly adjustable for slight modifications. The center piece of the Full Service Cock Cage is the stainless steel penis plug that can be inserted up to ##” but can also be adjustable at small increments as you learn to use it. The full cage also functions extremely well without the plug, making it an option you can play with as you wish. The Full Service dimensions are: Triple cock ring 2”x 1 7/8”x 1.5”. First ring on shaft cage is 1.5”, the second is 1.25”. The stainless steel penis plug offers up to 3.25” of maximum penetration when mounted in the cage or as little as you prefer. The penis plug is hollow and will let all your juices flow freely which they will most likely do the minute you are ready for Full Service.
