ELAN Shank Buttons are classic sew-on closures with a raised back shank that helps the button sit cleanly on thicker fabrics and layered plackets. This pack includes 1 buttons in 20 mm (3/4 in) for coats, sweaters, knitwear, uniforms, and craft projects where a secure attachment is needed. Hand-sew with a strong thread and reinforce for frequent wear, then test placement and tension before stitching on your finished garment.
