ELAN shank-back buttons add a clean finishing touch for coats, cardigans, knitwear, and accessories that need extra clearance at the closure. Each card includes 3 buttons measuring 15 mm (5/8 in) with a rear shank, letting you sew through the loop while keeping the face smooth. Match the size to existing buttonholes or loops, then reinforce heavier layers with a backing button and follow the garment’s care method.
