The Eureka! Cup Classic is a soft silicone menstrual cup that is designed to be respectful to both the environment and to your pelvic floor. The Eureka! Cups have been designed in Barcelona by accredited professionals in Sexuality together with a team of engineers from the Polytechnic University of Catalonia. The design of these cups was also done in collaboration with women of all ages, stages, and physiques. The softness of the Eureka! Cup also makes it beneficial for women who suffer regular UTI’s or who find firmer menstrual cups to be uncomfortable. If you would like a menstrual cup that does not need to be removed to be emptied, you may like to consider the original Eureka! Cup.

Eureka! Cup Classic Features:

  • Made from 100% medical grade silicone
  • Free from BPA, latex, chemicals or other derivatives
  • Soft, comfortable, flexible, and hypoallergenic
  • Designed with a few notches in the ring to help facilitate the insertion of the cup
  • Available in 3 sizes to accomodate different cervix heights and pelvic floor conditions
  • Can be worn for up to 8 hours
  • Maintains the natural vaginal flora
  • With proper care, the Eureka! Cup can last for up to 10 years

  1. Always wash your hands before handling or inserting your Eureka! Cup. Before first use, sterilise the cup in boiling water for 4 minutes.
  2. It is recommended to insert your Eureka! Cup while sitting, lying, standing, or squatting.
  3. If you are right-handed, hold the cup by its rim between the index finger and the thumb of the left hand. with the tip of the index finger of the right hand, bend the cup from any of its 4 notches to the deepest point of it (C-fold)
  4. Remove the index finger and grab the cup with your right hand without unfolding it. It is now ready to be inserted.
  5. Gently spread apart your labia with the left hand and insert the cup until it is completely inside the vagina (except for the tube/stem). Remove your fingers and the cup will pop open inside the vagina. You can also help the cup open by rotating the cup until you feel it has successfully unfolded.


  1. To remove the Eureka! Cup, pinch the base of the cup with two fingers. This will help remove the suction seal.
  2. Then gently pull the cup out of the vagina, using a side to side motion.
  3. Empty, wash and reinsert, or sterilise and store until your next period.


Inserting, emptying, and removing the Eureka! Cup can be a learning curve. We recommend getting used to your cup and finding the process that suits you best over a few cycles.

During your period, wash the Eureka! Cup with water and a scent and oil-free soap. The cup should be emptied and rinsed at least every 8 hours.

At both the end of your current period and the start of your next period, it is recommended to sterilize the cup. This can be done in a pot of boiling water, or by using the Sensual Intim Sterilizer.

Once cleaned, store the Eureka! Cup in it’s storage bag until next needed.

Correct maintenance of your menstrual cup will help prolong its life. Some staining is normal, however, it is time to replace your cup at any sign of deterioration to the silicone (ie. cracking, tearing, splits etc).

    Super great, but too soft for my needs.
