Thank you for viewing! Lesson bag: 30 x 40 cm, gusset 4 cm Shoe bag: 26 x 22 cm, gusset 4 cm Both are lined. The red polka dot part of the outer fabric is quilted. Please note that size changes are not possible. This is a set sale of the lesson bag and shoe bag; I apologize, but they are not sold separately (；＿；) Please refrain from purchasing if you are concerned, as this is a handmade item. If you would like to purchase other items I have listed at the same time, please comment. I will offer a discount. I'm sorry, but I'm not taking custom orders. I have other items from the strawberry-chan series listed, so I would be happy if you would take a look ☆ This year, this lesson bag set will be the only additional item listed, so I hope you find something you like from the remaining stock (*´꒳`*)
