Use these ELAN shank-back buttons for fine closures on shirts, childrens wear, light outerwear, and small accessories where a smooth button face is preferred. Each card supplies five 10 mm (3/8 in) buttons, giving enough pieces for a full front or for quick wardrobe replacements. Sew through the back shank, secure knots on the underside, and match the size to your buttonholes before stitching to avoid strain.
