Here is another result of many requests from our customers with random sized and shaped multi-ball style shaft urethral sound that also includes the unique hold-in-place valley, or groove, at the end next to the flange. With its gradually tapered mini ball style rounded tip and ribs this probe goes in smoothly allowing for individual control of depth. The total length is approximately 17" with a 16.5" insertable length (419mm) up to the flanged style base. This probe can be purchased with open core for extended length wear to accommodate drainage or with a completely solid configuration.

The sound has 22 separate expanded areas. Some are designed like small balls and others are gradually tapered out and back in to the shaft. They vary not only in diameter but shape and length including the uniquely tapered tip. The expanded areas vary slightly in diameter from between 7mm at the tip and 10.6mm at the maximum. The 15th rib enlarges to the maximum 10.6mm diameter and the last ball is approximately 10.4mm.

The tapered design of the last ball provides a gentle stretching action to allow the sphincter to
gradually stretch before seating itself into the 7.5mm diameter valley just in front of the flange. The primary sphincter just inside the urethral opening at the tip of the penis creates a perfect fit
and hold for those that can manage a 10mm sound.

The silicone material is available in many levels of softness as shown in the drop list selections. This sound should be extremely comfortable and quite functional for extended wear if that is what you desire.

As with all our other silicone nozzles, this one is also available in a wide array of material softness and colors. Please make note that the "00-50 Plus Soft" and the "10 Soft" silicones are not available in the pure translucent color. They are available in all the other colors including the translucent white material in the drop list. If you accidentally order one of those two softness selections with the normal translucent color option, we will automatically substitute the translucent white color instead. 

You can make your individual selections as to color, level of softness, and open or solid core type from the drop list boxes.
