In ordinary bottles when the liquid (e.g. hand-washing liquid) is about to finish, its last drops stick to the walls of bottle, making it hard to pour out so that the user usually doesn't bother himself to extract it out. This new package has a flat surface in its lower corner, making it possible to stand awry, gathering the remaining liquid in a place. These last drops then could easily flow out via the narrow groove on the side of the bottle. This product enables users to consume what they paid for, until the last drop, sustainably and green!
