ELAN shank buttons in 21 mm (7/8") size, supplied as a 2-piece card. The raised shank keeps thread protected and creates clearance so layers sit smoothly, making it a smart choice for coats, jackets, chunky knits and bag flaps. Use for closures on thicker fabrics or as a decorative accent. Sew through the shank loop and reinforce heavy layers with a backing button. Colours and surface finishes vary by style; choose a card that complements your fabric and buttonhole spacing.
