Buy FLEX Cup

FLEX logo cup is easy to use

  •    Position
    • Wash your hands and the FLEX Cup for 20 seconds. Press the sides of the cup together and then fold it in half again forming a tight ‘U’ shape.

    • OR place a finger on the top rim of the cup and press it down into the center making the top smaller for insertion.

  •    Insert
    • The FLEX cup folds for easy insertion, and then warms and forms to your body, creating a seal. Get in a comfortable position, relax your vaginal muscles, insert the FLEX Cup into your vagina, sliding it up and back toward your tailbone (not straight up).

  •    Check
    • Make sure the cup has opened completely by inserting a finger into your vagina and gently pressing on the side of the vaginal wall. You should feel no pleats or indentations. Creating space around it allows the cup to fully open.

  •    Wear
    • Go and live your life as you normally would! You can swim, exercise, and sleep wearing FLEX Cup. It collects up to three super tampons worth of fluid for up to 12 hours.

  •    Remove
    • Simply pull the ReleaseRing™ to break the seal and remove. The ReleaseRing™ pulls the top of the cup in to break the seal and help prevent spillage during removal. Before using or reusing, remove the ReleaseRing™ and thoroughly wash the cup for 20 seconds with warm water.

Questions & Answers
1. Why choose FLEX Cup?

FLEX Cup is the most comfortable and easiest to use cup on the market making it the #1 cup for beginners.

Not only is it sustainable and safe to wear for up to 12 hours but users can feel confident in removing the cup.

FLEX Cup's unique pull-tab makes removal easier than other cups and is also mess-free!

2. Is FLEX Cup good for heavy flows?

FLEX Cup is a great option for users with heavy flows. The Slim Fit holds the equivalent of 2 super tampons, while the Full Fit holds the same 3 super tampons’ worth of period blood. The cup's unique pull-tab also makes it easy to remove, empty, and reinsert on the heaviest of days.

The majority of our customers have heavy flows - including those with endometriosis and PCOS who swear by FLEX Cup!

3. Does removing FLEX Cup get messy?

FLEX Cup’s unique pull-tab assists with removal making it easier - and mess-free!

New users will also time their cup usage around their schedule in order to remove the cup in the comfort of their home or in the shower while they get the hang of it.

4. Can FLEX Cup be used with IUDs?

There is a small risk of any internally worn menstrual product getting caught on your IUD - including tampons, menstrual discs, and cups.

If you use an IUD, you should be informed about your particular IUDs benefits and risks and consult with your physician.

5. What's the difference between FLEX Disc and FLEX Cup?

Simply put: FLEX Disc is a menstrual disc and FLEX Cup is a menstrual cup.

A menstrual disc is a round, flexible ring with a catch that sits at the base of the cervix in a place called the vaginal fornix. A menstrual cup is a small flexible period collection device that sits in the vaginal canal and is typically tapered at the base.

Both the disc and the cup can be worn for up to 12 hours, but what you do once you take it out is another point of difference. The disc is disposable and single-use only, so you simply empty the contents and throw it away after a single use. With the cup, after emptying the contents, you clean it with soap and water and reinsert as directed.

Try FLEX with some liners at first.

Sometimes you just feel better with a little backup. FLEX plus liners would be a great combination for you while you transition to FLEX to help guard against leaks until you get the hang of positioning FLEX.
