Hesychia Ferumbound - Custom colorHesychia Ferumbound is an enhanced version of the classic Hesychia, featuring a 10mm steel bar that increases the rigidity of the device. While it retains the appearance of a traditional ball gag, its internal anatomical design completely fills the available space in the oral cavity, effectively restricting speech. The integrated metal element provides added stability, and leather strap attachments ensure secure fixation even during active sessions.
