Master Series Dark Invader Metal and Silicone Anal Plug (Medium) is a weighted anal plug combining nickel-free aluminum alloy with body-safe silicone. At 4 inches total with 3 inches insertable length and 1.3-inch maximum diameter, it conducts temperature for enhanced sensory play. The hybrid design suits intermediate users seeking substantial weight with extended wearability during solo or partnered exploration.
The Dark Invader's metal body conducts temperature naturally, warming or cooling within minutes of submersion in hot or cold water to create contrasting sensations during insertion and wear. The smooth, polished aluminum alloy surface glides effortlessly without friction while the tapered tip ensures gradual, comfortable entry. The silicone base flexes with your body's movement, preventing pressure points and discomfort during extended sessions that rigid designs cannot accommodate.
Nickel-free aluminum alloy delivers the substantial weight that intermediate users seek without triggering allergic reactions common with lower-quality metals. The non-porous construction supports thorough cleaning and maintains its lustrous finish through repeated use without degradation. Those exploring weighted options can discover our urethral plugs collection for additional sensations.

| Insertable Length | 3 inches (7.62 cm) |
| Maximum Diameter | 1.3 inches (3.3 cm) |

Pairing the Dark Invader with other forms of stimulation intensifies sensations that the weighted plug alone provides. Using it during masturbation or with a partner creates layered pleasure where internal pressure combines with external contact. Combining temperature play—alternating between warm and cool insertions—extends sensory variety across multiple sessions. The weight creates natural movement during partnered activities, generating subtle internal massage effects that many find uniquely pleasurable compared to static alternatives.
Clean the Dark Invader thoroughly with warm water and mild antibacterial soap before and after each use, ensuring both the metal body and silicone base receive complete attention. The non-porous surfaces prevent bacterial growth when properly cleaned, though specialized toy cleaner provides additional sanitization for peace of mind. Allow it to dry completely before storing in the provided pouch to protect the surfaces from dust and maintain separation from other items. Never expose the plug to extreme temperatures, freezers, or microwaves, as this damages materials and creates safety hazards.
Master Series Dark Invader features nickel-free aluminum alloy construction, eliminating allergic reactions common with lower-quality metals while delivering substantial weight that enhances internal awareness. The medical-grade silicone base contains no phthalates or harmful chemicals, meeting the highest safety standards for intimate products. Non-porous materials support thorough cleaning and prevent bacterial harboring, making this a hygienically responsible choice. The flared silicone base exceeds safety recommendations for anal plugs, preventing unwanted travel while remaining comfortable during extended wear sessions.
This plug suits intermediate users with some anal exploration experience seeking the unique sensations that weighted metal delivers. Those transitioning from all-silicone designs report dramatically different and more intense feelings from the added weight and temperature responsiveness. People interested in temperature play find the metal body's heat conductivity particularly appealing for expanding sensory variety. The medium size accommodates users comfortable with graduated stretching while still providing satisfying fullness, making it ideal for regular use without overwhelming proportions.
For those accustomed to silicone plugs that feel inert and unchanging, the Dark Invader's weight creates something fundamentally different—a constant internal awareness that intensifies with movement rather than remaining static. Many intermediate users report that discovering how substantial pressure transforms sensations shifts their understanding of what anal exploration can deliver. The hybrid design solves a practical problem that all-metal plugs create: extended wear discomfort from rigid bases pressing against sensitive tissue. By combining metal's weight and temperature conductivity with silicone's flexible comfort, the Dark Invader enables longer sessions where pleasure deepens rather than fading. For temperature play enthusiasts, the aluminum body's superior heat retention compared to silicone means sensations last longer and feel more pronounced, making investment in weighted metal exploration feel justified when standard options feel limiting.
Our independent testers evaluated the Dark Invader's insertion comfort, weight distribution, temperature retention, and base stability across extended wear sessions. The tapered tip provided smooth entry with proper lubrication, while the silicone base remained comfortable without shifting even during active movement. Temperature conductivity proved notably superior to silicone alternatives, with the metal body maintaining warmth or coolness for significantly longer periods.
Testers reported that the weighted design created measurable internal awareness during both solo and partnered activities, with the 1.3-inch diameter providing satisfying fullness without excessive stretching. The plug remained securely positioned throughout extended sessions, and the smooth finish eliminated any uncomfortable sensations. Individual results may vary based on anatomy, sensitivity, and usage.
