The Silicone Inflatable Double Bulb System is made of premium silicone and is designed for the enema enthusiast. The nozzle is inserted along with the first balloon. Both balloons are then inflated, creating an internal feeling of fullness and an external seal. Once the seal is created, liquid is filled inside of the rectum via a bag system or the Clean Stream In Line Accelerator. The premium silicone is ultra soft yet firm and flexible, for comfortable and body safe use. Each bulb has an integrated release valve for quick deflation and easy removal. Measurements: 17.5 inches in total length; Large bulb: 5 inches in length, 3 inches max diameter inflated; Small bulb: 1.75 inches in length, 2 inches max diameter inflated.
