XR Brands Creature Cocks Sinister Eyes Metal Butt Plug Set is a three-piece graduated metal anal plug collection featuring embedded glass eyes and temperature-responsive nickel-free construction. The set includes small (1.1-inch diameter), medium (1.3-inch diameter), and large (1.5-inch diameter) insertable widths, designed for progressive training and fantasy-themed visual appeal. Temperature play capability allows warming or cooling with water for sensory variation during solo or partnered exploration.
The Sinister Eyes plugs feature a mesmerizing glass eye embedded in each metal head, creating a visual fantasy element that peers outward during wear. The tapered metal tip slides in smoothly, while the flanged base prevents full insertion and keeps the plug securely in place during movement or extended wear. Nickel-free metal construction ensures compatibility with sensitive skin while the non-porous surface conducts temperature naturally for warming or cooling sensations before use.
Metal construction offers durability and weight that silicone plugs cannot match, providing substantial pressure without requiring muscular tension to hold in place. The graduated sizing allows progressive exploration, starting with the small plug for comfort and advancing to larger sizes as your body adapts. Those exploring anal training can browse our wear-all-day anal plugs for extended-wear options.

Pairing the small plug with external clitoral stimulation or a vibrator creates layered sensation that many find more intense than either alone. For those exploring anal training, the graduated set allows progression to the medium plug after several sessions with the small size, building capacity gradually. Combining temperature play with the plugs—warming one in warm water before insertion—adds sensory dimension that enhances arousal and awareness during solo or partnered exploration.
Clean the metal and glass surfaces with warm water and mild soap after each use, paying special attention to the glass eye and base crevices where lubricant residue accumulates. Ensure all water is completely dried from the surface and glass before storage. Store in a clean pouch or container away from extreme temperatures, which can affect the metal's conductivity. These plugs are compatible with all lubricant types, though water-based formulas clean away most easily.
Nickel-free metal construction ensures body safety for people with sensitive skin or metal allergies, while the non-porous surface prevents bacterial absorption and supports easy cleaning. The glass eye remains securely embedded and poses no safety risk during insertion or wear. The tapered tip, narrow neck, and flanged base design prevents over-insertion while maintaining comfort during movement, making this set appropriate for anal training without requiring advanced experience.
This set suits people interested in fantasy-themed anal play with visual appeal and progressive training capacity. Those with sensitive skin benefit from nickel-free metal construction, while people exploring temperature play appreciate the metal's natural heat conductivity. The graduated sizing appeals to beginners seeking gentle progression alongside those experienced with anal play who want fantasy elements combined with functional design and durable construction.
For those curious about anal exploration but uncertain where to start, graduated sizing removes the pressure of choosing one size that might be too large or too small. The small plug allows initial comfort assessment without intimidation, while the progression pathway means your investment grows with your experience rather than requiring multiple separate purchases. For people frustrated by silicone plugs that feel lightweight or lack visual appeal, the metal construction combined with the embedded glass eye transforms anal play from purely physical sensation into fantasy-driven arousal. The temperature responsiveness adds psychological engagement—warming the metal before insertion creates anticipation, while cooling it heightens initial sensation and awareness. For those exploring anal training as a couple, the visible glass eye creates psychological connection and shared visual interest during partnered play, making the experience feel collaborative rather than isolating.
Our independent testers evaluated the set's construction quality, temperature conductivity, insertion comfort across all three sizes, and visual appeal during wear. The tapered tips slid smoothly with adequate lubricant, while the flanged bases remained secure during movement and extended wear without discomfort.
Testers confirmed that warming the metal in warm water created noticeable temperature sensation upon insertion, while cooling produced heightened awareness of initial contact. The glass eyes remained securely embedded with no movement or loosening after repeated use. Individual results may vary based on anatomy, sensitivity, and usage.
