This Dittle Sounds Set is a kit that includes eight 10.5 inch urethral sounding instruments made of medical grade stainless steel. These sounds are quite long, with one flat end that is easy to grasp.

Dittle sounds are measured in the French scale (also called the French gauge system), which is commonly used to measure the diameter of catheters. It is most often abbreviated as Fr. The French size is three times the diameter in millimeters. A sound of 15 French, for example, would have a diameter of ​5 mm.

Sizes in this set are 8 Fr through 22 Fr, in 2 Fr intervals.

Comes with a black zipper case with velvet lining for storage.
