LEONA AIR FLOW is a menstrual cup which is easier to remove than other cups. One of the biggest problems facing users of the menstrual cup is the difficulty of removing the device. The basic design has remained the same since its invention in 1937. It has taken over 80 years to address this problem, but we have finally come up with a solution. When a user presses the air valve in the base, air flows through the cup and out through ultra fine holes near the rim, releasing the seal. The size of the holes is so small that it does not allow the flow of liquid such as water or blood, however, air is still able to pass through. The user is able to control the strength of the seal which helps to reduce abdominal bloating.
