Abstract: A storage bag to wrap dirty objects such as diapers (including sanitary napkins and the like) without dirtying one's hands. Furthermore, by attaching the bag to a diaper, used diapers can be directly wrapped. The components include a strip of flexible water-resistant sheet material divided into three sections and folded twice in the same direction, and sealed at the sides, and the bottom of the bag attached to the outer upper portion of a diaper.
