The Beppy Cup has a capacity of 25ml (up to the anti-leak flap) - 30ml (under the hole). Although the cup has a size comparable to the size S/M, the Beppy Cup has a capacity of almost an L size cup. This is due to the innovative design. Regular cups are tapered at the bottom, while the Beppy Cup is wider at the bottom. Because of this, more menstrual fluid can be collected.
During an entire menstrual period, a woman loses on average 20-80ml of blood. When a woman loses more than 120ml of blood during a normal menstrual cycle, this is called severe blood loss.
