The TENGA AERO series consists of two reusable adult toys for men. One part of the plain body acts as a dial to control the air flow inside the device. When it is activated, an internal valve is adjusted to free or restrict air flow, controlling the vacuum function. A ring embedded in the inner sheath provides additional stimulation through a constriction and suction function. After cleaning, the sleeve can be stored hygienically on the accompanying drying stand, which is built into the protective cap.
