8 pc Dittel Urethral Dilator Sounds kit ranging from small (8 fr) through large (22 fr). They are stainless steel and come in a zipper case for storage. Each unit comes with a flat handle on one end for greater control when there is lots of lubrication around.
Someone once said that the flat side was for attaching Electro Stim connections, but that must be just an evil rumor! You would never do that to your subbie would you!!?
Made of stainless steel, can be autoclaved.
