This is a foldable insulated cooler bag. When folded, it's a compact shoulder bag measuring 10cm x 15cm. When unfolded, it has a large capacity with a width (top: 40cm, bottom: 30cm), height of 27.5cm, and a depth of 27cm. How about taking it with you on your travels? I think it will be very useful. Please consider purchasing, understanding that it has been stored at home.
