MeLuna Classic Menstrual Cup with ball stem (Large, Clear)
The material of the MeLuna Classic has a softness of 40 Shore (a term for describing the flexibility of plastic). A menstrual cup must unfold, or "pop open" completely inside the vagina to form a seal. The cup's material should be firm enough to unfold inside the vagina while being surrounded by the vaginal muscles, but at the same time the material should not be unpleasantly hard. A menstrual cup should not cause any feeling of pressure when in place. Ideally, a menstrual cup should be soft enough to fold easily, with enough resilience to "pop open" inside the vagina. If you have any questions, please contact me through the MeLuna website.
