Blue Line Stainless Steel Peephole Penis Plug 1 3/4 Inch Length with Bulb Tip

Medical-Grade Construction

This urethral sound is manufactured from surgical-grade stainless steel, offering the non-porous, autoclavable surface required for safe urethral play. The polished finish eliminates microscopic surface irregularities that could harbor bacteria, while the material's durability ensures the device maintains its integrity through repeated use and sterilization cycles.

Anatomical Specifications

The sound measures 1.75 inches (44.5mm) in total insertable length. The bulbous tip features a graduated diameter designed to facilitate initial urethral dilation, transitioning smoothly to the shaft diameter. The hollow-core construction creates a through-hole (peephole) that runs the entire length of the device, allowing for continuous urethral drainage during wear and providing visual feedback during insertion.

The bulb tip serves a specific anatomical purpose: its rounded profile reduces the risk of urethral tissue trauma during insertion compared to straight-tipped alternatives, while its slightly enlarged diameter provides tactile feedback when passing through the urethral sphincter.

Design Features

Hollow Core Design: The continuous channel through the center permits urination while the sound remains in place, distinguishing this device from solid urethral sounds. This feature allows for extended wear scenarios while maintaining normal urological function.

Tapered Profile: The gradual diameter transition from tip to shaft facilitates progressive urethral stretching, allowing tissue to accommodate the device at a controlled rate.

Polished Finish: The mirror-polished surface minimizes friction during insertion and removal when used with appropriate sterile lubricant.

Temperature Responsiveness

Stainless steel's high thermal conductivity allows for temperature play applications. The device can be warmed in water (never exceeding body temperature initially) or cooled to provide varied sensory experiences. Always test temperature on sensitive skin before urethral insertion.

Essential Safety Parameters

Urethral sounding requires strict adherence to sterile technique. This device must be thoroughly cleaned and sterilized before each use. Use only sterile, surgical-grade lubricant specifically formulated for urethral application. Never force insertion—advancement should occur smoothly with gentle, consistent pressure. Discontinue use immediately if resistance, pain, or bleeding occurs.

The 1.75-inch length is appropriate for external urethral exploration but will not reach the bladder in most anatomies, reducing certain insertion-related risks.

Maintenance Protocol

Clean immediately after use with antibacterial soap and warm water. Sterilize through boiling (10 minutes), autoclave, or chemical sterilization before subsequent use. Store in the included protective pouch to prevent surface contamination and damage.
