Embassy replacement button in 18 mm (3/4") with a classic shank back that lifts the button slightly above the fabric for clearance on thicker cloth and knits. Supplied as a useful 3‑pack when garments include a spare button. Ideal for coat and jacket replacements, knitwear finishing, bags, uniforms, costumes and everyday mending. Smooth, rounded edges are presser‑foot friendly and easy to hand‑sew for beginners or pros.
