Blue Line 3.5 Inch Blue Stainless Steel Penis Plug

Product Overview

This urethral sound is manufactured from surgical-grade stainless steel and finished with a blue PVD (Physical Vapor Deposition) coating. The device measures 3.5 inches in total insertable length and features a gradual taper from tip to base, designed for controlled depth progression during urethral insertion. The decorative blue metallic finish distinguishes this sound visually while maintaining the hygienic properties of the underlying medical-grade steel.

Materials and Construction

The core material is 316L surgical stainless steel, recognized for its biocompatibility, corrosion resistance, and non-porous surface properties. The blue PVD coating is a durable, body-safe surface treatment that does not flake or chip under normal use conditions. The entire surface is mirror-polished to eliminate microscopic irregularities that could harbor bacteria or cause tissue irritation during insertion.

Stainless steel sounds offer several advantages for urethral play: they are fully autoclavable, compatible with all lubricant types, and provide weight and temperature conductivity that many practitioners find enhances sensory feedback during use.

Design Specifications

Dimensions:

• Total insertable length: 3.5 inches (89 mm)
• Tip diameter: approximately 4 mm
• Base diameter: approximately 8 mm
• Taper: gradual conical progression

Weight: Approximately 28 grams

The tapered profile allows practitioners to control insertion depth according to their experience level and anatomical capacity. The flared base serves as a safety feature, preventing over-insertion and providing a grip surface for controlled manipulation.

Safety and Usage Considerations

Urethral sounding requires specific knowledge of urethral anatomy and sterile technique. This practice should only be undertaken after thorough research into proper sterilization protocols, appropriate lubricant selection, and anatomical landmarks.

Essential safety protocols include:

• Complete sterilization before each use (autoclave, boiling for 10+ minutes, or chemical sterilization)
• Use of sterile, water-based urethral lubricant specifically formulated for this application
• Never force insertion—the urethra will accommodate the sound when properly relaxed and lubricated
• Awareness of urethral anatomy, including the external meatus, navicular fossa, and membranous urethra
• Immediate cessation if pain, resistance, or bleeding occurs
• Proper post-use cleaning and storage in a sterile environment

Urethral play carries inherent risks including urinary tract infection, urethral trauma, and potential stricture formation if performed incorrectly. Consultation with healthcare providers familiar with this practice is strongly recommended, particularly for those new to sounding.

Care and Maintenance

Clean immediately after use with antibacterial soap and hot water, paying particular attention to the tapered shaft. Sterilize using your preferred method before storage. The PVD coating is permanent and will not degrade with repeated sterilization cycles. Store in a dedicated container away from other materials to prevent surface scratches.

Inspect before each use for any surface irregularities, coating damage, or structural defects. Do not use if any imperfections are detected.
