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 black, and the stitching color is blue. The number of holes in the belt is either 4 or 5, depending on the spacing of the holes on the school backpack's original belt. The extension length is up to 15cm. Semi-custom orders are made to fit your size. Size confirmation is required. When purchasing, please provide the length from the tip of your school backpack's belt to the first hole, and the spacing between the holes. Please refer to images 7 and 8 for details.
