Although it doesn't have a lining, it's made of canvas material, so it's durable and has a sturdy construction. Width 43cm x Height 36.5cm (when laid flat). It has a 2-3cm gusset, so it can hold a lot of luggage. It's the perfect size not only for nursery schools, kindergartens, and elementary schools, but also for bags for extracurricular activities like cram schools and piano lessons. - Design: Humming Mint - Material: Canvas - Damage: Fading on the gusset, small fraying on the front, and traces of an iron-on name tag. Thank you for viewing. I bought this for extracurricular activities, but I switched to a backpack after using it for a few months, so I no longer need it. Please purchase if you understand that this is a used item. If you have any questions, please feel free to comment. Thank you very much (*´꒳`*)
