Thank you, m☺︎-sama! (>◡<) This is a black lesson bag, a shoe bag, and a pianica case. The sizes are: Lesson bag: 29 x 38 cm, gusset 4.5 cm (A3 size is not available) Shoe bag: 27 x 19 cm, gusset 4 cm Gym clothes bag: 34 x 30.5 cm *Please note that there may be a difference of a few millimeters to 1 cm in size. The exterior is made of quilted fabric, and the lining is made of nylon fabric. The handles are securely sewn with an X stitch to prevent them from coming off, so they should be able to withstand heavy loads. The lesson bag is large enough to hold an art box, and it's short enough to hang on the side of a desk without dragging on the floor. The shoe bag is a large size that can be used until the 6th grade. The two are made of the same fabric. The items will be folded for shipping, so there may be creases. I made these with care, but as they are handmade, there may be some slight imperfections. Thank you for your understanding before purchasing. I have made multiple items with the same fabric, so please note that the pattern placement may differ from the photos. Thank you for your consideration!
