These ELAN sewing buttons are designed for everyday garment repairs, tailoring, costumes, and new makes at home. Each retail card includes 2 buttons sized 18 mm (3/4 in) in diameter for matching closures on shirts, jackets, knitwear, dresses, uniforms, or bags. Use sturdy thread, reinforce stitches on the reverse side, and confirm buttonhole fit and spacing on a fabric scrap before washing or dry cleaning.
