Description
Sei Mio Open Invitation is an O-ring gag that keeps the mouth held open instead of filling it with a solid ball. The sturdy silicone ring sits between the lips, leaving the centre open for direct mouth access while making clear speech more difficult.
A padded vegan-leather strap wraps around the head & closes with an adjustable hook-and-loop fastening. The soft padding helps reduce irritation around the face, while the secure strap keeps the ring positioned once fitted. Nickel-free metal hardware finishes the black bondage look.
The open-centre format creates a very different feel from a traditional ball gag. There is no large ball occupying the mouth, yet the ring still imposes a clear restraint by holding the jaw open. It is a strong choice when mouth access is part of what you want from the gag.
Agree a clear non-verbal stop signal before fitting the gag. Check the wearer regularly to make sure they can breathe & swallow comfortably, and never leave a gagged person unattended.
