How works.


The FLEX cup folds for easy insertion, and opens up inside to form a seal with your body.


It collects up to 3 super tampons’ worth of fluid for up to 12 consecutive hours.


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.
