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 has a curve to increase sensation as it glides up and down. For more advanced players, Pratt sounds can reach the prostate. 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. The set comes with eight different sounds all with 11.5" (29.2 cm) insertable lengths and the total length is 12" (30.1 cm). The fine steel shafts come in a variety of sizes ranging from 4.5mm, 5mm, 5.5mm, 6mm, 7mm, 7.5mm, 8.5, 9mm, 9.5mm, 10mm, 11mm, 12mm, 11.5mm, 12.5mm, 13.5mm, and 14mm wide. Since these are made of stainless steel you can boil them for 3-5 minutes to sterilize them.
