Your clothes, bag, car, floor will never get wet when you close the Rainy Umbrella from a downpour. The dry side of the umbrella will come outside and the wet side will come inside when it was closed .
Never get stuck when you close the Inverted Umbrella after you get on a car or any covered space, and your arm still keep dry.
Self stand: when you don’t have much floor space to drip up an umbrella, just put it at a little corner. It will stand up by itself without wet the wall.
