This ELAN sewing button pack is designed for repairs, replacements, and finishing work on apparel, knitwear, and accessories. Each card includes 3 buttons in 15 mm (5/8 in) to match common sizes on shirts, sweaters, costumes, and light outerwear. Confirm buttonhole fit and placement before sewing, and reinforce stress points on heavier fabrics to help the closure last, especially on frequently used garments and accessories.
