The Klaas Open Hollow Anal Plug Size M from Afterdark is crafted for experienced explorers who crave deeper, more immersive anal stimulation. Its hollow core unlocks a unique sensation profile, delivering intensified internal contact and a subtle suction-like feedback for heightened arousal and awareness.

• Open hollow core: Central hollow channel creates expanded sensations and suction-related feedback that amplifies arousal and tactile awareness during use.
• Size M for confident progression: Sized to move beyond beginner plugs, with overall dimensions of 9.6 cm long by 9.5 cm at its widest to balance presence and control.
• Long neck + bulbous shape: The extended neck guides deeper insertion while the bulbous tip concentrates stimulation for focused pleasure.
• Wide base for safety and removal: A broad base stays outside the body for safe handling and straightforward removal, even during extended sessions.
• Lubrication & care compatibility: Designed for use with water-based lubricants; clean before and after use with dedicated toy cleaners (Nanami N-507, N-996, or N-997) and dry completely before storage.

This hollow design matters because it alters the sensation landscape, providing more than a standard plug by increasing internal contact and adding subtle suction feedback that can heighten arousal. It’s an ideal next step for those comfortable with longer insertion and a larger base, offering a controlled path to deeper exploration. Pair it with a trusted arousal routine or partner-led exploration to maximize the hollow channel’s effects, and maintain safety with careful inspection of the neck and base before each session. Regular cleaning with the recommended Nanami cleaners and use of a quality water-based lubricant help maintain material feel and longevity, so you can explore with confidence and consistency.
