This is a lesson bag featuring a print of dinosaurs and stars. Size: Approximately 40 cm wide Approximately 30 cm long There is no gusset or inner pocket. Please note that the color may appear different depending on your monitor. The lining is a natural-colored quilted fabric. It's a bit thick and should last a long time. Since I'm selling it at a low price, it may be compressed for shipping due to shipping costs. Thank you for your understanding. I make each item carefully, but there may be slight imperfections.
