ELAN shank buttons suit closures where the button needs lift off the fabric, helping layered plackets and thicker materials fasten more smoothly. This card includes 3 buttons sized 15 mm, with a raised shank back that gives thread clearance and reduces bulk at the buttonhole. Confirm the buttonhole size and placement before sewing, then secure with strong thread and a few locking stitches for a tidy, durable finish.
