Ando expandable bags are handmade in Japan for all you need to carry the day. They start off pocket-sized so they're easy to have on hand, then they expand to tote-sized in seconds. This is all thanks to the careful Japanese Shibori technique. The cloth is tightly bound around penny-sized rings, washed, then steamed to get those disk-like wrinkles and their versatile stretch. When you're done, the bags scrunch back down and keep their shape for next time.
