ELAN shank buttons are dependable fasteners for coats, jackets, knitwear, bags and structured garments, keeping thread protected and the button face smooth. This card includes 1 button sized 20 mm (3/4″) with a rear shank that lifts the button above thicker layers so closures sit flat and drape cleanly. Hand‑sew through the shank; match the diameter to existing buttonholes and test placement, tension and spacing so the closure moves freely without strain on the fabric.
