The Fetish Fantasy Spider Gag in steel is suitable for you if you have previous experience using gags.
The part that goes in the mouth on this gag is made as an O-ring, which sets its design apart. The ring sits behind the teeth so that it doesn't fall out.
On the ring there are 4 metal spikes mounted that sits close to your face when you use it. These spikes ensure that the ring does not disappear into your mouth.
The gag is held in place by a strap that sits behind the head. The strap is adjustable to heads with a circumference up to 59.5 cm. You can fasteb it in 10 different holes.
The o-ring for the mouth has an outer diameter of 4.5 cm.
