1st.- To right-handed, hold the Eureka! Cup by its crown between the index finger and the thumb of the left hand. With the fingertip of the right hand, bend the Eureka! Cup from any of its 4 tabs, to the deepest point of it. It will be folded.
2nd.- Extract the index finger without unfolding, and take the Eureka! Cup with the right hand. Find the position that is most comfortable for insertion into the vagina.
3rd.- Separate the vaginal lips with the left hand and enter the Eureka! Cup until it is whole inside the vagina (except the tube). When you remove your fingers, the Eureka! Cup will unfold inside the vagina. To help this happen, you can rotate the Eureka! Cup until you notice that it has been deployed successfully. You can check around the Eureka! Cup with your finger.
4.- Insert the tube into the vagina, with the help of fingers, until it is absolutely upright. The Eureka! Cup will be sealed and ready to enjoy it.
