backpack

Abstract

As shown in the "reference back view showing the names of the parts," this item is made up of a right and left piece of fabric that touches the back, with the left edge of the right fabric and the right edge of the left fabric overlapping front to back in a free state, forming a slit-like opening, which can be opened by pulling the right fabric to the right and the left fabric to the left, as shown in the "reference back view with the opening open," allowing items to be put in and taken out. As this item has no openings other than the back, it has excellent security and is resistant to rain getting inside.
