This ELAN shank button is made for garment sewing, repairs, and accessories where extra clearance helps the closure sit comfortably over thicker layers. The card includes 2 button(s) sized 20 mm (3/4 in), with a raised back shank to keep stitches off the front and reduce wear at buttonholes or loops. Hand-sew with strong thread, check the fit against the finished buttonhole, and reinforce the attachment on heavy fabrics for dependable fastening.
