ELAN shank-back button lifts the button face slightly, helping closures move smoothly on thicker fabrics, layered plackets, and knitwear with bulk. Card includes 3 buttons sized 15 mm (5/8 in), with a rear shank that hides stitching and creates clearance for coats, cardigans, structured tops, and bag flaps. Attach with strong thread and a thread stem if needed, confirm the buttonhole or loop size before sewing, and clean according to the garment label for consistent wear.
