Doc Johnson Girthmasterr 8.5-inch dildo in dual-density ULTRASKYN, molded directly from the performer's body, with a removable Vac-U-Lock suction cup base.
Part of the Doc Johnson Signature Cocks line. Dual-density ULTRASKYN: firm inner core under a softer outer skin that warms to body temperature with use. The shaft is shorter than Brickzilla but built around girth, with realistic veins, a defined head, and the performer's body proportions. Removable Vac-U-Lock suction cup base sticks to flat surfaces or fits a Vac-U-Lock harness. Ships with a Doc Johnson drawstring storage bag, a care guide, and a Vac-U-Powder sample.
Why this works
- Built around girth instead of length, so the stretch is the point and the insertable depth stays manageable.
- Dual-density ULTRASKYN: firm core with a softer outer layer that warms with use.
- Molded directly from Girthmasterr, so the shaft proportions match the performer.
- Vac-U-Lock base detaches for either suction-cup play or harness-compatible strap-on use.
- Phthalate-free per Doc Johnson. O-ring harness compatible.

Care
Wash with mild unscented soap and warm water before first use and after every session, or use a toy-safe spray cleaner. ULTRASKYN is porous, so it cannot be fully sterilized; treat it as a single-user toy or cover with a condom for sharing. Dust lightly with Vac-U-Powder (or unscented cornstarch) once dry to keep the surface smooth. Store in the included bag away from other silicone toys.
Use it for
Solo play, partner play with a harness, suction-cup hands-free play, girth-curious users who want stretch over length.
FAQ
What's it made of?
ULTRASKYN, Doc Johnson's dual-density TPE blend with a firm inner core and a softer outer layer. Phthalate-free per Doc Johnson. Porous, so single-user or condom-covered for sharing.
How thick is it?
Width/Diameter: 2.25 in. Built for girth rather than length at 8.5 inches total. If you're stepping up from a slim or beginner dildo, expect noticeable stretch. Use plenty of water-based lube and work up slowly.
How does the Vac-U-Lock base work?
The suction cup twists off the base. Used with the cup on, it sticks to smooth flat surfaces. With the cup removed, the exposed Vac-U-Lock peg fits any Vac-U-Lock compatible harness.
Is it harness compatible?
Yes. Vac-U-Lock harness via the peg under the suction cup, or a 2-inch O-ring harness with the suction cup left on.
Will it warm up?
Yes. The soft outer layer of ULTRASKYN warms to body temperature with use.
What lube should I use?
water-based or hybrid. Water-based is the safest default with ULTRASKYN and rinses off cleanly between sessions.
How do I clean it?
Easiest: spray with a toy cleaner and wipe down. Otherwise mild unscented soap and warm water before first use and after every session. Air dry fully. Don't boil or dishwasher ULTRASKYN. A light Vac-U-Powder dust keeps the surface smooth.
Is it discreet?
All orders from The White Unicorn ship in a plain package. The return label will read TWU or shipping department.
