Made of stainless steel, these urethral sounds are easy to sterilize and body safe for an enjoyable sounding experience. These rods glide with the body, sliding down your shaft for that unique sensation that you crave.

Each sound is double-sided, with a different sized girth on each end. The graduated sizes allow you to work your way up until your urethra can accommodate the largest rod. The sounds come in a practical leather, velvet-lined case. Each sound is in graduated sizes starting from 3.5mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm. Hegar sounds are 8" (20.3 cm) in total length. Since these are made of stainless steel you can boil them for 3-5 minutes to sterilize them.
