Thank you for viewing my listing. I will strive to make our transaction a pleasant one. Thank you for your understanding. This is a handmade randoseru (Japanese school backpack) shoulder cover. I referred to the recipe from "Harimogura no Ouchi Jikan" (Hedgehog's Home Time) ^_^ As this is a handmade item, there may be some imperfections, but 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 Randoseru Shoulder Covers⭐︎ By softening the contact surface between the shoulder belt and the shoulder, it reduces the burden of weight and prevents the shoulder from digging in and causing pain. For children who walk long distances to school, or who have a school route with many slopes and stairs, shoulder pads help to reduce shoulder pain ^_^ #Randoseru #ShoulderCover #ShoulderBelt
