This gag and mask combination is a real treat for the senses. Inhibit the sight by wearing the silicone blackout eye mask and prevent full speech with the 1.75 inch diameter silicone gag. Both parts of this set come with easily adjustable straps that clip together at the back. The gag is open-mouthed which enables easy breathing and also allows for the possibility of other mouth adventures. This silicone set is also tasteless, odourless, non-porous and hypoallergenic. One size fits the majority.
