This ELAN shank button pack is intended for sewing closures where added clearance helps on layered fabrics, knitwear, and accessories. The card includes 5 buttons in 9 mm (3/8 in) diameter for repairs, replacements, and matched sets on garments. Confirm placement and fit before stitching, and store remaining buttons with your notions so the same size is on hand for future mending, especially on frequently used garments.
