This ELAN shank button is made for garment sewing, mending, and accessory finishing where a raised shank helps it sit cleanly over thicker fabrics. Each card includes 3 buttons sized 15 mm (5/8 in) with a shank construction, suitable for shirts, knitwear, uniforms, and light outerwear when you need a classic round fastening. Sew by hand or machine with thread matched to fabric weight, and test placement on a scrap to confirm buttonhole fit and stitch tension before final stitching.
