It's time to persuade everyone to be eco-friendly by having one of these in their briefcase, handbag etc and say  “no more plastic bags” needed when shopping. When not in use, the bag is folded and rollup in a case which only takes 10 Cm space. When it's unfolded, it can stretch to 32 x 40 Cm generous space for you to put lots of shopping stuff in, be it a pair of jeans, grocery and many more item . When it is dirty, you can hand wash it and hang it dry naturally then it can go back to service again! Its durable material will last a long time.
