This ELAN sew-through button pack is made for garment construction and repairs on shirts, dresses, cardigans, and accessories. It includes 2 buttons in 20 mm (3/4 in) to keep scale consistent across front openings, cuffs, and small closures. Check spacing and buttonhole fit before final sewing, and keep any extras on the original card so replacements stay easy to match, especially on frequently used garments.
