This is a urethral dilator sound set with 8 sounds made from chrome-plated brass. Each sound has a different sized end. The set offers sixteen sizes, ranging from 3 to 19 millimeters in diameter.
The purpose of this sound set is to gradually and gently enlarge the urethra, when inserted. The sounds can also be used in other areas other than the urethra, such as anally, vaginally or prostate. Each set comes in a zippered velvet lined case for storage between each orgasmic session.
