The MK II Blast Balls plug by American Bombshell. The plug is made of PVC and features three grenade-like thickenings, connecting pieces with stimulation ridge and a firm handle. Due to its girth we advise against using it if you are a beginner. This firm plug is very flexible and great for duo games due to its length. The MK II Blast Balls plug makes all your fetish and SM fantasies a reality.
