ELAN two-hole sew-through buttons are designed for everyday garment and craft closures where you want a low-profile, easy-to-stitch finish. This card includes 4 buttons measuring 12 mm (1/2 in) across, ideal for shirts, cuffs, knitwear, children’s wear, accessories, and quick repairs. Sew by hand or with a machine button foot using sturdy thread, and add a small backing button or extra passes on stress points for durability; keep small parts away from children.
