※ The elastic part is approximately 30 cm. Simply hook the buttonholes on both ends of the belt onto the belt loops of the pants you are wearing and close the buttons. The size can be adjusted freely to accommodate your child's growth. It can be worn in a perfect size for children of any body type. It's safe because you don't need to remove the belt when changing clothes for gym class, especially when using the restroom. The entire belt is made of elastic, so it stretches and doesn't feel tight around the stomach, providing excellent comfort. It can be used with pants other than school uniforms, for both boys and girls. - Colors: Black, Stripe - Materials: Synthetic leather, stretch material - Design: Striped design, adjustable - Size: Adjustable Thank you for viewing.
