Thank you for viewing my listing. I will strive for a smooth transaction, so thank you in advance. This is a handmade shoulder cover for a school backpack. 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. Quilt batting inside, quilted lining Easy to attach with Velcro ♫ Approximately 22cm long x 18cm wide When attached, width 5-5.5cm ⭐︎Benefits of school backpack shoulder covers⭐︎ By softening the contact surface between the shoulder strap and the shoulder, it reduces the burden of weight and prevents the strap from digging into the shoulder and causing pain. Shoulder pads can help alleviate shoulder pain for children who walk long distances to school, or who have a school route with many hills or stairs ^_^ #SchoolBackpack #ShoulderCover #ShoulderStrap
