ELAN brand sewing button set sized 15mm (5/8"). Shank buttons have a raised loop on the back that provides thread clearance so thicker fabrics drape smoothly and the button face avoids abrasion. Each retail card includes 3 buttons in 15mm (5/8"). Use for clothing repairs, replacements, or new makes including shirts, cardigans, uniforms and light outerwear. Check buttonhole size before installation and test placement on a fabric scrap.
