Thank you for viewing. This is a handmade lesson bag. The cotton fabric (oxford) is reinforced with a non-woven adhesive interlining on the back. Lined with sheeting. The gusset is made large enough to accommodate an art box. Compared to quilted fabric, it is thinner, so it can be folded compactly and stored when not in use. Size: 40 x 25cm Gusset: 8cm *Limited-time sale price until the end of the year. #LessonBag #Blue #DinosaurPattern #Handmade #Entrance/Enrollment #PictureBookBag Type...Lesson Bag
