Thank you for viewing from among many items. This is a handmade lesson bag. Size: 30cm x 40cm, gusset 4cm (slight variations may occur) Perfect for entering school, extracurricular activities... How about it? I make each item with care, but as it is handmade by an amateur, there may be some distortion or fabric unevenness. Please purchase only if you understand this. I am currently raising children, so I may be slow to respond to questions, but I will try my best to respond quickly and politely. Please excuse any wrinkles from storage or shipping. This item is stored at home, so please purchase only if you understand this. I do not negotiate prices. There may be slight variations in size. Please ask any questions before purchasing. Shipping is not available on Saturdays, Sundays, and holidays. ◆ I have various other items for sale, so please take a look if you'd like.
