  • Care

    Flex Cup Care: During your period, start with clean hands and wash your cup with the warmest water you can stand and some mild soap or Flex Foaming Cup Wash. Pro-tip: To clean the inside of your cup, fill it with that same soapy blend and place a palm over the opening. Swish that around for a minute or two, making sure that water runs through the air holes located on the top of your cup.

    Before and after your period, boil your cup for 10 mins in a large pot, stirring from time to time. Make sure it doesn't come in contact with the sides or bottom of the pot, as that could melt the silicone.

This product has been a game-changer for me! I love using this cup as opposed to tampons.

There are so many menstrual cups on the market and it can be hard to choose which one is best. There's definitely a learning curve with any cup, but I can say this one is the easiest to remove by far, which I find super helpful!
