Tampons are vaginal inserts which are cylindrical in shape. But why a tampon, exactly? Tampons are a good choice because they're small, almost unnoticeable, and swim-safe. Johnson and Johnson’s O.B ProComfort Tampons are made up of dense layers of highly absorbent fibers that are interwoven to keep them bound. O.B Pro Comfort Tampons are safe and easy as they widen to provide a tight, gap-free fit. OB Tampons can help avoid staining incidents and vaginal odor by providing the right pH balance and level of protection for you. The structure of a woman's body and the flow of her menstrual cycle varies from one female to the next. For first-time non-applicator tampon users or women with mild to moderate flow, O.B Pro Comfort REGULAR is ideal. PRO COMFORT O.B. Tampons with Fluid-Lock grooves vouches for leak safety that is locked in. For ultimate comfort and glide, choose tampons with SilkTouch cover (O.B Pro Comfort Tampons!)
