Thank you for viewing! This is a handmade lesson bag. To avoid being cheap and poorly made, I've selected a fabric with a moderate thickness for the check pattern, so you can use it with confidence for six years. It comes with a navy lining (broadcloth) for a smooth and durable finish. It doesn't take up much space and can be folded and stored in a school bag. *This is the page for the green check pattern. *Size Approximately 30 x 40cm *You can add a 3cm or 5cm gusset. It's an additional 150 yen. Please comment before purchasing. *Fabric Navy part: Twill Lining: Broadcloth ☆★You can change the navy fabric to a thicker, more durable Katsuragi fabric. It's an additional 150 yen. Recommended when you put in heavy items like picture books or sheet music! Katsuragi is a fabric characterized by a beautiful weave that gives a luxurious finish. *You can wash it at home using a laundry net. *Each item is carefully handmade, but due to the handmade nature, there may be slight size errors or individual differences. I also have matching shoe bags, drawstring bags, lunch bags, lunch mats, and mobile pocket bags, etc. on sale. #handmadesunnyandharmony Please take a look☆ ★If you are considering size changes or bulk purchases, please read the profile before commenting to consult with me★ Piano bag Lesson bag Picture book bag Handbag Gym clothes bag Changing clothes bag Familiar familiar Miki House MIKI HOUSE Ralph Lauren RALPH LAUREN Bebe BEBE Mezzo Piano Pomponette Kumikyoku KUMIKYOKU
