This fiendish-looking device is actually used by dentists and oral surgeons to keep a patient's mouth open during examinations and surgeries. However, fetishists and bondage fans often find this type of device interesting for other reasons.
This item was designed as a medical/dental device. It cannot be expected to fully function as a secure gag, although it might be effective in some cases. Adding your own strap around the back of the head – such as a leather thong – it is possible to make this somewhat secure.
Many people will want to own this simply as a collector's piece. However, others will want to use them in play; caution is necessary. Use care and common sense, and proceed slowly.
All stainless steel.
