Key is a well-known sex toy brand in the United States, and its China business is operated by Wuhan Renfu Health Care Industry Co., Ltd., which received tens of millions of yuan in orders at the 2012 Las Vega Adult Products Show in the United States. KEY materials are well-known in the industry, and the quality of products at the same price is much higher than other brands, so it is very popular.
 
At present, KEY still sells fewer aircraft cup products, only two series: European Cup and pubic buttocks double hole. The European Cup series has its own characteristics according to the national style. The front and back of the cup can be inserted, and the suction cup can also be installed on the wall to free your hands, and the fuselage comes with a 3.5mm headphone jack, which can be inserted into the headphones and you can also hear the sound feedback brought by the different insertion speeds, and it will not be monotonous and boring when used.
 
The price of KEY aircraft cup is 60-250 yuan, which is a low and medium price, but compared with other brands, the functionality still needs to be improved, and the diversity needs to be strengthened.
