ELAN brand sewing button set sized 10mm (3/8"). Shank buttons have a raised loop on the back that creates thread clearance, helping thicker fabrics drape smoothly and reducing abrasion on the button face. Each retail card includes 3 buttons in 10mm (3/8"). Use for clothing repairs, replacements, or new projects including shirts, cardigans, uniforms, and light outerwear. Check buttonhole size before installation and test placement on a fabric scrap.
