Flatfish bag is a circle handbag whose profile is embedded with a ring-shaped zipper.
Flatfish bag is composed of four parts: piece a(with zipper head), piece b(without zipper head), zipper, and replaceable handle/strap. The zipper can completely separate the bag into piece a and piece b. These two pieces come in various colors and patterns, and can be freely replaced, combined, and can be purchased separately.
Flatfish bag interacts with its customers and allows them to alter the appearance of the bag.
