These are supposed to eliminate that string line from around your waist when wearing thongs. Basically giving you a pantiless look while still covering up your naughty bits. They're held in place by tape. Yes tape.
They look a little like diapers or maybe sanitary pads...but... Go commando without risk of exposure! They're a little expensive at over $30 each...but what the hell I'll give it a whirl.
