With appropriate use and maintenance, MeLuna menstrual cups have shown in a wear test conducted by a third party lab, that they can withstand a minimum of 3 years of wear. Many users have kept their MeLuna in great shape for many more years! Due to FDA regulations we can only claim use life that has been substantiated in third party testing. Testing is expensive. That's why we only tested for 3 years.Please note: cups are not perishable. The manufacture date is on the box to allow us to track cups in case of a recall. Manufacture date is not relevant to use life. Use life begins when use begins. Generally we count the purchase date as the beginning of the 3 year use life.Excessive exposure to UV rays will cause MeLuna to get brittle, which is why it should be kept out of the sun.

Yes. TSS cases in menstrual cup users are not common but they are possibleA few years ago a French study indicated that frequent disinfection may decrease infection risk. The study suggested to change to a fresh cup every 6 hours. To make this practical it would be best to have 4 cups in rotation and disinfect them once a day. We do offer a 10% discount for any cup purchase or 2 or more menstrual cups to make this approach more affordable. The Consumer Reports summary can be found here

Once You Have Your MeLuna Menstrual Cup

TPE cups turning oval and is completely normal!
As long as you have an adequate diameter the cup turning oval does not cause leaking.
Why does the cup turn oval?
TPE is short for thermoplastic elastomer. It means the material adjust to its surroundings under the influence of heat including body heat. The vagina is shaped like a compressed tube rather than a round pipe, hence the cup becomes oval to match its surroundings.
