Eco bag Nylon eco bag with a piano keyboard design, convenient with a zipper that can enlarge the bag. Flat: Approximately 40 x 40 cm. Smaller when the zipper is closed. Approximately 26 x 40 cm when in use. It has been unfolded for photography, but it is unused. I have two and am selling the extra one. It's useful because you can make it bigger depending on the amount of shopping! 850
