The Masters Series Manus Intruder is a dual-stimulation cock ring with integrated anal plug, crafted from medical-grade stainless steel. The 2.05-inch inner ring diameter and 1.25-inch plug diameter deliver simultaneous restriction and fullness, while the temperature-responsive metal surface supports warming or cooling for sensory variation. It suits people seeking premium construction with extended wear capability and temperature play integration.
The Masters Series Manus Intruder combines cock ring restriction with anal plug insertion in a single integrated device. The stainless steel construction conducts temperature naturally, allowing the surface to be warmed or cooled before use for added sensory contrast. The polished metal surface enables smooth insertion while the weighted feel provides heightened awareness during extended wear.
Medical-grade stainless steel with chrome-plated construction offers durability and a luxurious feel that plastic alternatives cannot match. The non-porous surface supports complete sterilization and maintains its polished finish through repeated use. Those seeking additional options can find our steel cock rings range at Adultsmart.

Pairing the Masters Series Manus Intruder with a prostate massager can create layered internal stimulation that many find more intense than either product alone. For partnered play, the dual-stimulation design allows one partner to control penetration while the ring provides continuous restriction, creating shared rhythm and sensation. Temperature play—warming the metal under warm water or cooling it in the refrigerator—adds sensory dimension that enhances arousal before insertion.
After use, clean the surface thoroughly with warm water and mild soap, paying particular attention to the bridge and ring interior where lubricant accumulates. Ensure all lubricant residue is removed, then dry completely with a soft cloth. The non-porous stainless steel can be fully sterilized by boiling for five minutes, running through a dishwasher cycle, or using an autoclave. Store in the provided pouch in a cool, dry location away from other materials that might scratch the polished surface.
Medical-grade stainless steel construction ensures the Masters Series Manus Intruder is non-porous, hypoallergenic, and completely body-safe for internal and external contact. The chrome-plated steel plug resists corrosion while maintaining smooth surface texture. It remains compatible with all lubricant types and supports complete sterilization through boiling, dishwasher, or autoclave methods, making it suitable for shared or long-term use without degradation.
Suits people seeking simultaneous cock ring restriction and anal stimulation in premium materials without compromising on durability or aesthetics. This product appeals to those experienced with individual cock rings or anal plugs who want integrated dual stimulation without managing separate devices. The precise engineering and extended wear capability make it ideal for people prioritizing comfort during longer sessions and those interested in temperature play exploration.
For those frustrated by plastic cock rings that rattle or flex rather than deliver consistent restriction, the solid stainless steel construction transmits pressure steadily without flexing or deforming. The weight feels substantial enough to maintain position without requiring constant adjustment, reducing the attention needed to keep it properly seated during activity. What once felt like managing two separate products—ring and plug—becomes a single integrated experience where restriction and fullness work together, letting sensation build naturally rather than feeling compartmentalized. For people accustomed to silicone alternatives, discovering how metal's thermal properties add warmth or coolness without batteries or heating elements expands what intimate exploration can offer. The durability means this investment maintains performance and appearance indefinitely, unlike plastic devices requiring eventual replacement.
Our independent testers evaluated the Masters Series Manus Intruder for material durability, comfort during extended wear, temperature conductivity, and positioning stability across different body types. The stainless steel maintained its polished finish after repeated sterilization cycles, and the bridge length accommodated varied anatomy without requiring adjustment or causing pressure points during 45-minute wear sessions.
Testers confirmed that the 1.25-inch plug diameter provides noticeable fullness without causing discomfort during insertion or extended wear, while the 2.05-inch ring diameter delivered consistent restriction without circulation impairment. Temperature play testing showed measurable temperature change when the device was warmed or cooled, with sensations persisting for 10-15 minutes before normalizing to body temperature. Individual results may vary based on anatomy, sensitivity, and usage.
