We've updated the design. Extension belts for school backpacks, designed for children who grow quickly. Made of genuine leather, so they are durable and look beautiful. The belt color is light blue, and the sewing thread color is also light blue. The number of holes in the belt is either 3 or 4, depending on the spacing of the holes on the school backpack's main belt. The extension length is 15cm. Semi-order products are made to fit your size. Size confirmation is required. When purchasing, please provide the length from the tip of the school backpack's belt to the first hole, and the spacing between the holes. Please refer to images 9 and 10 for details. #SchoolBackpack #SchoolBackpackExtensionBelt #SchoolBackpackShoulderBelt #SchoolBackpackShoulderBeltExtension #ExtensionBelt #SchoolBackpackBelt
