This ELAN button set is designed for clothing repairs, new sewing, and accessories where you want a tidy, classic button closure without added bulk. Each card includes 3 button(s) in 15 mm (5/8 in) with a four-hole design, suited to shirts, knitwear, uniforms, bags, and general craft use. Confirm the diameter against existing buttonholes before attaching, and secure stitches firmly with suitable thread so the closure stays aligned through regular wear.
