The SSND-SPEAR-B 12" & 16" is engineered for deep internal expansion and gradual urethral stretch. Featuring a smooth main body topped with a soft, flexible spear head, this precision-molded sound transitions from a narrow 4mm entry tip up to a heavy 15mm maximum diameter across its 2" tapered lead section. Classified as an Advanced urethral sound based on its 15mm (45 Fr) maximum diameter profile, it delivers high-contact feedback for experienced users requiring substantial expansion.

Anatomical Sizing & Mechanics

  • Entry Tip: Starts at a slim 4mm (12 Fr) rounded lead tip to allow soft, low-resistance entry into the meatus.

  • Shaft Progression: Tapers smoothly over a 2" head section from 4mm up to its peak 15mm (45 Fr) profile.

  • Peak Diameter: Reaches a full 15mm outer diameter, creating an advanced dilation profile along the main shaft.

  • Main Shaft: Continuous, sleek 15mm working length with no ribs, ridges, or valleys for a uniform glide.

  • Safety Flange: Integrated base flange provides an external stop to prevent over-insertion and ensure controlled retrieval.

Anatomical Depth Guide Available in total lengths of 12" and 16". The initial insertable section navigates through the penile urethra into the prostatic urethra and bladder region, requiring advanced skill and careful technique to navigate deep anatomical curves safely.
