    So glad I ordered

    I’ve been using as a back up for leaks on heavy days using tampons when I can’t change it on time as it’s been a real annoyance, but now it’s not something I have to worry about

    No show

    The pale pink underwear is the nicest invisible colour I’ve ever found. A little brighter than a nude but not so much to show through light colored pants.

    Got the job done

    Effective for light bladder leakage but the crotch area is a little stiff. Not uncomfortably so but enough to notice.
