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 2 buttons sized 15 mm (9/16 in) 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.
