Classic shank buttons sized at 13 mm (1/2") with a smooth back loop that protects the thread and lets the button pivot easily. Ideal for jackets, cardigans, uniforms and accessories where a clean front surface is desired. Use them to replace missing buttons or finish handmade garments and bags. Each card includes 2 button(s) for quick repairs or coordinated closures. Compatible with hand or machine sewing using standard thread. Colour may vary by style.
