These ELAN 2-hole button are basic sewing notions for garment repairs, replacements, and new makes. The buttons measure 23 mm (0.91 in) in diameter and use a 2-hole sew-through design suited to shirts, knitwear, outerwear, and accessories. Each card includes 2 button(s) per card, which helps with coordinated closures or quick replacements, so match the diameter to your buttonholes and stitch with thread suited to the fabric weight for a durable closure.
