Embassy shank buttons feature a built‑in loop on the back to create space between button and fabric. This 3‑pack measures 15 mm (5/8 in) across and is designed to prevent puckering and help layered fabrics drape cleanly. The smooth face offers a tidy, elevated look and is easy to grasp. Sew them onto coats, cardigans, knitwear, bags and costume pieces for durable closures that won’t compress bulky layers.
