It's like a portable toilet. If you don't want to poop or pee on a public toilet, you carry it in your purse and when you gotta go, find a private place (preferrably) and unfold it and do your business. It has 100 plastic liners in the "bowl" so you can just throw the refuse away in a trash can or dump it in an actual toilet and it folds back up and goes back into your purse.
