This ELAN shank button adds a slightly raised closure that leaves space between button and fabric, making it useful on layered plackets, knitwear, outerwear, and structured accessories. The card includes 4 buttons in a 12 mm (1/2 in) diameter, with a built-in loop back that is designed to be hand-sewn on securely with standard sewing thread. For best hold, anchor the stitches well and test the buttonhole fit so the fastening sits neatly without pulling at thicker seams.
