DA KAKA 3-WAY Backpack 40L 【Brand New】 This was a gift. The size is approximately 31cm wide x 20cm deep x 55cm high, measured by an amateur. It's a 3-way bag, so it can be used as a backpack, shoulder bag, or handbag. I am also listing this on another site, and I will remove it if it sells there. Thank you for looking.
