Thank you for viewing my item from among many others. This is a tool bag with a ribbon and stripe pattern. It has a 6cm gusset, so I think it can also be used as a dictionary case (^-^) The height of this one is 20cm. ☆Tool Bag☆ Height → Approximately 20.5cm from the gusset Width → Top, approximately 32.5cm Bottom with gusset, approximately 26.5cm Gusset → 6cm The outer fabric is oxford cloth. The lining is natural-colored #11 canvas fabric. It's more sturdy than two layers of oxford cloth. I think the specified size varies depending on the school, so if the size fits you, please consider it. m(_ _)m I would be happy if someone likes it(*´∀`) Thank you for viewing. Type...Lesson Bag
