This ELAN sew-through button is a simple two-hole closure for apparel sewing, repairs, and small craft projects. The card includes 4 button(s) in 15 mm (5/8 in), sized to coordinate with common buttonholes on shirts, knitwear, and accessories for wardrobe refreshes and coordinated replacements. Choose thread that matches the fabric weight, position for smooth alignment, and confirm the diameter fits the buttonhole before laundering or pressing.
