SSND-RNDMBALL 7-10mm - 21-31Fr Random Ball 8'' & 17" Deep Sound

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. We have two available lengths for this item at the moment with our original 17" with a 16.5" insertable length (419mm) up to the flanged style base and our newer 8'' model. This probe can be purchased with an open core for extended-length wear to accommodate drainage or with a completely solid configuration.

The 8'' sound has the same diameter as the first 12 separate expanded areas of our 17'' model with comes with 22 separate expanded areas. Some are designed like small balls, and others are gradually tapered out and back into 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 stretch gradually 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.
