A Closer Look at the Mortal Coil Master Series Urethral Sound & Plug

Forged from surgical-grade stainless steel, the Mortal Coil Master Series Urethral Sound & Plug is the pinnacle of precision urethral play. Its brushed finish glides effortlessly while progressive swells along the shaft dial up intensity with each inch inserted. A central thru-hole lets fluids pass freely—and a handy ring pull ensures clean, confident retrieval. Ready to defy your limits? Welcome to the next level of cock and ball torment.

Key Features & Benefits of This Stainless Steel Urethral Sound & Plug

  • Progressive Swells: Graduated bulges deliver pinpoint stimulation—each swell teases new nerve endings.
  • Thru-Hole Design: 0.10″ (2.5 mm) internal channel allows uninterrupted urination or ejaculation.
  • Temperature Play: Steel conducts heat or chill—warm in water, cool in the fridge for sensory contrast.
  • Ring Pull Retrieval: Secure loop ensures safe, controlled removal—even under maximum intensity.
  • Master Series Quality: Non-porous, hypoallergenic stainless steel resists bacteria, ideal for repeat medical fetish play.

Measurements

  • Total Length: 6.63 in (16.84 cm)
  • Insertable Length: 5.13 in (13.02 cm)
  • Maximum Diameter: 0.49 in (12.45 mm)
  • Internal Channel Diameter: 0.10 in (2.5 mm)
  • Material: Surgical-grade stainless steel
  • Color: Brushed Grey
  • Weight: 0.23 lbs (≈0.10 kg)

What to Expect

Insert the tapered tip and feel the first swell—an electrifying pressure that intensifies as you sink deeper. The thru-hole ensures no interruption, while the ring pull remains easily accessible. Whether you lean into the burn of cold steel or the warmth of heated metal, every moment is a calculated thrill.

Safety and Preparation Guidelines

  • Use only sterile, water-based lubricant on both the sound and your urethra.
  • Sterilize by boiling briefly or soaking in medical disinfectant before and after each use.
  • Insert slowly, stopping at any sharp pain or resistance; never force deeper than comfort allows.
  • Monitor for any numbness or discoloration; remove immediately if circulation is compromised.
  • Legal Disclaimer: For novelty use only; no warranties—use at your own risk.

Compatibility Information

  • Lubricants: Water-based only. Avoid silicone, oil, or alcohol-based products that can irritate or damage tissue.
  • Cleaning: Rinse under warm water with mild soap; air-dry completely before storage.
  • Storage: Store in a padded pouch away from direct sunlight and other metal toys to prevent scratches.

FAQs About the Mortal Coil Urethral Sound & Plug

  • Is this suitable for beginners?
    No—designed for intermediate to advanced users familiar with urethral play.
  • Can I temperature-play safely?
    Yes—immerse in warm (not scalding) water or chill briefly in the fridge; never use extremes.
  • How do I clean the internal channel?
    Run warm soapy water through the thru-hole, then disinfect and rinse again to ensure hygiene.
  • Will the ring pull irritate?
    It’s smoothly welded; any discomfort is usually from improper insertion angle—adjust slowly.
  • Can I wear this under clothing?
    Not recommended—its weight and rigidity make it a play-session device, not a stealth concealer.

Shipping, Billing & Privacy

Last Updated: August 2026

Your privacy travels with every order

From the moment you check out to the moment your package arrives, every step is designed so that what you buy stays entirely between you and us.

How we appear on your statement

  • Credit / Debit Card: Sp-Tdh-Br
  • PayPal: TDH Retail Ltd

Some banks may display a slightly different or truncated version of these descriptors — this is determined by your financial institution and is outside our control.


What Discreet Shipping Means

Every package we send is prepared with your privacy in mind. If someone sees your order on your doorstep, in your mailroom, or being carried by you, they will have no way to know what’s inside. Even carrier employees handling your package cannot tell from the exterior that it contains intimate products.

  • Plain Packaging: Orders are shipped in standard brown cardboard boxes or plain poly mailers, with no decorative branding.
  • No Branding: No product names, logos, or “TheDildoHub” branding appear on the exterior of your package.
  • Carrier Markings Only: The only external markings are the shipping label and carrier tracking information required for delivery.

Plain cardboard shipping boxes used for discreet packaging

Our Shipping Boxes

We use cartons from Stock Box Company and other established packaging suppliers. The specific packaging used may vary depending on your order’s size, weight, fulfillment location, and availability. Using cartons from different suppliers does not change the discreet nature of your shipment.

All boxes used for shipping are plain, unbranded, and selected to provide appropriate protection during transit. The Stock Box Company cartons pictured above are single-wall boxes supplied from Santa Fe Springs, California. Their printed certification states that they meet the construction requirements of the applicable freight classification.

The certification shown on these cartons lists the following specifications:

  • Bursting-Test Rating: 200 pounds
  • Minimum Combined Facing Weight: 84 pounds per 1,000 square feet
  • Maximum Size Limit: 75 inches
  • Maximum Gross Weight Limit: 65 pounds

These specifications apply to the pictured Stock Box Company cartons. Other boxes may have different manufacturer specifications, but all packaging used for your order is selected for safe transit and maintains the same plain and discreet presentation.

For suitable smaller or lighter shipments, we may use padded poly mailers instead of cardboard boxes. These mailers are also plain and unbranded, with no externally visible product descriptions.


Free Shipping

Free Super Saver Shipping applies automatically to all U.S. orders over $139 — no promo code needed. Every free shipment receives the exact same discreet packaging treatment as any paid tier. Your privacy is never a function of how much you spend.


Order Processing

All orders take 1–2 business days to process before they ship. Orders placed with Express, Priority, or Rush shipping are processed on the next business day. Processing time is separate from transit time, and the delivery estimates for each shipping method begin once your order has been packed and handed to the carrier.

Orders placed on weekends and federal holidays begin processing on the next business day.

  • Processing Time: 1–2 business days for all orders. Express, Priority, and Rush orders are processed the next business day.
  • Tracking Updates: Tracking information may take 24–48 hours to update after your order ships. If it hasn't moved after 48 hours, contact us.

Shipping Rates

All rates are flat per order — not calculated by weight. The same price applies whether you're in Manhattan or rural Alaska. TheDildoHub covers any additional carrier costs; you will never be charged more than the rate shown at checkout.

Domestic Shipping — United States

All 50 states · APO/FPO/DPO · U.S. Territories · PO Boxes

Method Transit Time Price Typical Carriers & Services
Super Saver (Free) 7–10 Business Days Free (>$139) USPS Ground Advantage, FedEx Ground Economy, UPS SurePost, OnTrac Ground
Economy 5–7 Business Days $10.95 USPS Ground Advantage, FedEx Ground, FedEx Home Delivery, UPS Ground, OnTrac Standard

Rush 1–2 Business Days $64.95 USPS Priority Mail Express, FedEx 2Day, FedEx Overnight, UPS 2nd Day Air, UPS Next Day Air Saver

Transit times begin after your order ships — processing time is not included. Times are estimates; carrier delays, weather, and peak volumes can affect delivery. If significantly delayed, contact us and we'll make it right.

About our domestic carriers

We use USPS, FedEx, UPS, and OnTrac for reliable nationwide shipping. Our fulfillment team automatically selects the best carrier based on your location, speed, and package details. You cannot select a specific carrier, but every carrier delivers in plain, unmarked packaging.

  • FedEx: Ground Economy, Ground, Home Delivery, Express Saver, 2Day, Overnight
  • UPS: SurePost, Ground, 3 Day Select, 2nd Day Air, Next Day Air Saver
  • USPS: Ground Advantage, Priority Mail, Priority Mail Express
  • OnTrac: Ground, Standard, Express

Why is Super Saver slower than Economy?

Super Saver uses the most cost-efficient routing available at the time of fulfillment — typically consolidators or ground services with longer transit windows. Paid tiers use faster, dedicated carrier services. The same discreet packaging applies regardless of speed.

Military address shipping (APO/FPO/DPO)

TheDildoHub is proud to serve American servicemembers. All military shipments go exclusively via USPS as required by military postal regulations. Tracking is always available. Delivery may take additional time due to military postal routing, but every shipment leaves with the same discreet packaging standards.

PO Box delivery

Yes, we ship discreetly to PO Boxes across the nation via USPS. In our experience, PO Box deliveries may take a little longer — typically 1–2 additional days at most.

Delivery instructions

You can add delivery instructions at checkout. Please note that while we pass these on to the carrier, we cannot guarantee they will be followed in all cases. If delivery privacy is a concern, we recommend selecting a tracked speed so you can monitor arrival.

Why we don't guarantee delivery dates

No carrier can truly guarantee delivery in practice. Even express services are subject to delays from weather, carrier volume, and other factors outside our control. Stating estimates rather than guarantees avoids confusion. If your shipment is significantly delayed, we'll work with you to make it right.
