Classic ELAN shank button measuring 12 mm (1/2″) in diameter, supplied on a retail card of 2. The shank‑back design preserves a smooth face on the garment and provides consistent thread clearance for easy fastening. Ideal for coats, knitwear, handbags and costume work, and for replacing missing buttons. Sew on by hand through the shank; choose needle and thread appropriate for your fabric weight and test placement on a scrap before attaching.
