If a menstrual cup is smooth is it a good thing?
As with all menstrual cup features, the smoothness or texture of the menstrual cup varies according to the design and brand of the cup. While some cups are developed to be all smooth from the rim, bell, and stem others have textures on the cup. Smooth cups are known to be comfortable, however some reviewers of various brands of menstrual cups note that having a smooth cup can cause issues with grasping, gripping the cup for the process of removal.
