This unisex 2 piece gag and mask set is made out of stretchy, skin friendly silicone. The comfortable silicone bondage mask covers the eyes and blocks out all incoming light. The open mouth gag allows easy breathing but inhibits speech. The sturdy 1.5 inch diameter o-ring keeps the mouth open for other possibilities. Both parts of the set have clips which are easily adjustable and hook together with sturdy plastic clamps. This set is also phthalates and latex free, odourless and tasteless. One size fits the majority.
