Thank you for viewing my listing. I will strive to make our transaction a pleasant one. This is a handmade shoulder cover for a school backpack (randoseru). I used the recipe from "Harimogura no Ouchi Jikan" as a reference. As this is a handmade item, there may be some imperfections. Please consider purchasing only if you understand this. It has a quilted batting inside and quilting on the lining. Easy to attach with Velcro ♫ Approximately 23cm long x 18.5cm wide When attached, it is 5-5.5cm wide ⭐︎Benefits of school backpack shoulder covers⭐︎ By softening the contact surface between the shoulder straps and the shoulder, it reduces the burden of weight and prevents the straps from digging into the shoulders and causing pain. Shoulder pads can help alleviate shoulder pain for children who walk long distances to school or have a school route with many hills or stairs^_^ #SchoolBackpack #ShoulderCover #ShoulderStrap
