The Hegar Sound Set is a urethral dilator sound set with a full set of 8 sounds. Each sound has a different sized end, thus 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 into the urethra for such dilation. Each set comes in a zippered velvet-lined case for storage between each orgasmic session.
