Here's how: 

1. Wash your hands with soap and water. 

2. Choose a comfortable position, whether squatting, standing or sitting. 

3. Fold the KoraCup into your favourite shape. 

4. Loosen up: relax the pelvic floor muscles and breathe deeply. 

5. Now insert the folded KoraCup into your vagina. The cup should be positioned correctly in the centre of the vagina and NOT directly in front of the cervix. 

6. Let go. Did it pop? Then the cup has unfolded properly and a vacuum has formed. Now the cup stays tight and in place. 

7. Wash your hands again to remove the cup, assume a comfortable position and feel for the stem with your fingers. 

Caution: do not simply pull, but gently push the cup in sideways with one finger to release the vacuum. 


Safety instructions: The cup must not be worn during postpartum flow. The cup must also be removed during sex. Never use the cup if it causes pain, in case of pain please contact a doctor directly. Toxic shock syndrome (TSS) is an infection that can lead to severe organ and circulatory failure. It is caused by a bacterium. When this bacterium enters the bloodstream through an open wound or the uterus, it forms a toxin that causes shock in the body and can be fatal. Most known cases of TSS occurred during menstruation. Signs of TSS include fever, vomiting and diarrhoea, but also sunburn-like symptoms. If you experience any of these symptoms, remove the cup immediately and go to a doctor and/or the emergency room.
