Stainless steel sounds that slide straight down your dick. Just use our sterile lube and go slow (to start).
This style of sound (i.e., Pratt Sounds) differ from our Dittel Sounds in three ways. First, the rods are slightly curved; the bend in the rod is designed to enable slightly deeper urethral penetration. Second, the sounds are hollow -- therefore they should never be sanitized by immersing them in boiling water (instead pick up a bottle of our Cavicide Disinfectant Spray.) Third, these sounds are double-ended: both tips are smooth and rounded (thus, insertable), and each half of the sounding rod is a different diameter (in increments of one millimeter). For this reason, our Pratt sounds are listed in sizing pairs (see guide below).
